APPENDIX IV: EVALUATION OF STATISTICAL MODELS FOR ANALYZING THE DATA OF PET PRODUCT STUDIES

Background

Since the data are simulated as the number of blood-fed arthropods given the total number of infesting arthropods per animal, a generalized mixed-effects model (GMM) with logit-link function for binomial distribution appears to be the appropriate statistical model to analyze the data.  Although this statistical model (i.e., binomial GMM with a logit-link function) is conceptually appropriate, it does not directly generate estimates for the calculation of efficacy and its 95% confidence interval. However, GMMs with the log-link function for either the binomial distribution or Poisson distribution does generate the statistical estimates that can be easily used to estimate efficacy and its 95% CI.  Therefore, the original power vs. sample size simulations were conducted using GMM for Poisson distributions.  However, there are theoretical issues when using GMMs with log-link function for the binomial distribution or for the Poisson distribution to analyze the data of Pet Product study.  A GMM with a log-link function (a non-canonical link function) for the binomial distribution will sometimes produce the 95% CI of estimated proportion of blood-fed arthropods (or efficacy) which is bound between 0 and 1 outside the [0,1] range (this issue is not critical since EPA would only use the estimated rate ratio and its lower 95% CI to calculate the efficacy and its lower 95%CI).  A GMM with log-link function for Poisson distribution theoretically assumes that the counts have no limit for upper bound value (which never happens in reality) while the count of blood-fed arthropods is bounded from 0 to the total number of arthropods infested on the animal in most of the times (sometimes, the total count of arthropods at the end of testing is greater than the original number arthropods infested on the animal).

After reviewing the results of simulations based on the GMM for Poisson distribution data and GMM for binomial distribution data with log-link function, Dr. Jonathon Cohen, a statistician from ICF, has provided mathematical derivation to estimate the efficacy and its 95% CI using estimates from GMM for binomial distribution with logit link function.  Dr. Cohen also provided SAS code and some quick simulations to demonstrate using the binomial GMM with logit link function.  

In this appendix IV, we present a complete set of simulations for comparing 5 models: GMM for Poisson, GMM for binomial with log link function, GMM for binomial with logit link function, GMM for Poisson with "NOBOUND" option, and GMM for binomial with logit link function and "NOBOUND" option.  The last two GMM models with "NOBOUND" options, which allow the estimates of covariance matrices to be negatives, were included to address potential concerns with the zero value estimates in the covariance matrices of some datasets.  Each model was used to analyze each full dataset including the data of 2 groups on 4 testing days (called a full model).  When the full model failed to converge for a dataset, a separate model was used to analyze the data by each day. The separate models were consistent with the full model except they did not account for the repeated effects.  The separate models converged in most cases.
The simulations included 1000 random datasets for each of sample sizes (8, 9, and 10 animals/group) x each of 5 study designs (blood-fed proportions = 0.45, 0.60, 0.75, and 0.85).  The criteria to evaluate the models are as following: 
 number of converged datasets  -  higher is better;
 number of datasets with positive definite G matrices- higher is better;
 the power to determine the efficacy of a product to be acceptable based on the EPA criteria to determine the acceptance of a product: an estimated efficacy >= 0.90 and a precision <= 0.05.  From a practical perspective, a model that would result in a low probability of accepting a product when the true efficacy of the product is less than 0.90 and would result in a high probability of accepting a product when the its true efficacy >= 0.90 is more desirable;
 and most the important criterion, the logic of the model that is appropriate to analyze the data.

Summarized Results of all Simulations
Tables A4.2-1 and A4.3-1 present the results of number converged datasets and number of datasets with positive definite G matrices for the simulations when the random animal effects and random day effects were generated from Weibull distributions and normal distributions, respectively.  
 GMM model for Poisson distribution has highest number of converged datasets.  
 All models have low proportions of datasets with positive definite G matrix.  However, the GMM model for binomial distribution with logit link function has highest number of datasets with positive definite G matrices.

Tables A4.2-2 and A4.3-2 present the power of the 5 evaluated models.
 Despite the indicated theoretical issues, all models have acceptable probabilities (< 0.05) of accepting a "fail" product, i.e. accepting a product that has a true efficacy of 0.85 < the required efficacy of 0.90 (Type I Error) 
 When the random (animal and day) effects were generated from Weibull distributions
 The GMM for binomial distribution with logit link function has higher power than other models when the blood-fed arthropods in the control group = 0.45.
 The GMM for Poisson distribution has higher power than other models when the blood-fed arthropods in the control group = 0.60, 0.75, and 0.80.
 The GMM for Poisson with "NOBOUND" option, GMM model for binomial distribution with log link function, and GMM for binomial distribution with logit link function and "NOBOUND" option have lower power than the GMM for Poisson distribution and GMM for binomial distribution with logit link function.
            
 When the random (animal and day) effects were generated from normal distributions
 The GMM for binomial distribution with logit link function has higher power than other models.
 The GMM for Poisson with "NOBOUND" option, GMM model for binomial distribution with log link function, and GMM for binomial distribution with logit link function and "NOBOUND" option have lower power than the GMM for Poisson distribution and GMM for binomial distribution with logit link function.
            
Due to the mixed results in power between the GMM for Poisson distribution and GMM for binomial distribution with logit link function, the simulations for the power of GMM for binomial distributions were performed for different study designs (2000 datasets for each scenario).  The results of these power simulation are presented in Tables A4.4-1, A4.4-2, A4.5-1, A4.5-2, A4.6-1, A4.6-2, A4.7-1, A4.7-2, A4.8-1, and A4.8-2.  The results of these power simulations for GMM for binomial distributions with logit link function are summarized and presented with the power results of simulation for GMM for Poisson distributions (Appendix I) in Table A4.1.  The required sample sizes for using GMM for Poisson distribution are robust to the assumed distributions (normal or Weibull) of random animal or day effects.  However, the required sample sizes for using GMM for binomial with logit link function vary depending on the assumed distributions of random animal and day effects. Perhaps the GMM in the current SAS PROC GLIMMIX assumes the random effects are normally distributed, the power/sample size of the GMM with logit link function for binomial distributions are different depending on whether the random effects are generated from normal distributions or Weibull distributions.  When the random animal effects and random day effect were generated from normal distributions, the required sample sizes for using GMM with logit link function for binomial distributions are similar to required sample sizes for using GMM for Poisson distributions.  These are the sample size recommended for the study designs.

Mathematical derivation of the estimated efficacy using a binomial model with logit link function (provided by Dr. Cohen)

Using the binomial model with the canonical logit link, the probability that an insect is blood fed is given by the equations:
Logit Pbloodfed=logPbloodfedPnot bloodfed=μ+groupg+dayd+group*daygd
P is Probability. In this model, μ is the intercept, groupg is the effect for group g (either the treatment or the control group), dayd is the effect for day d (1, 2, 3, or 4), and group*daygd is the group*day interaction term. The logarithms are natural logarithms. The control group is group 0 and the treatment group is group 1.
For day d, define the logits for the control group and treatment group by
α=μ+group0+dayd+group*day0d,
β=μ+group1+dayd+group*day1d.
For the SAS coding we also define the total
τ=α+β
so that the covariance between the estimates of α and β can easily be calculated.
It follows that on day d,
Pbloodfed for a control animal=11+e-α ,
Pbloodfed for a treated animal=11+e-β ,
Efficacy=1-Pbloodfed for a treated animalPbloodfed for a control animal=e-β-e-α1+e-β=f(α,β)
Let α,β, and τ be the estimated values of α,β, and τ, and let their standard errors be seα,seβ, and se τ . The estimated efficacy is f(α,β). To approximate the standard error of the efficacy we can apply the delta method, a first order Taylor series expansion using the partial derivatives of f (see Klein, 1953 or Oehlert, 1992, for example):
Estimated efficacy= fα,β≈fα,β+(α-α)dfdα(α,β) +(β-β)dfdβ(α,β).
This gives:
Estimated efficacy ≈fα,β+(α-α)e-α1+e-β +(β-β)-e-β1+e-α1+e-β2 
Therefore the variance of the estimated efficacy is approximately given by:
Variance Estimated efficacy≈Varαe-α1+e-β2 +Varβ-e-β1+e-α1+e-β22+2 Cov(α,β)e-α1+e-β-e-β1+e-α1+e-β2
Taking the square root and replacing the unknown true values of the parameters by their estimates gives
Standard Error Estimated efficacy≈Varαe-α1+e-β2 +Varβ-e-β1+e-α1+e-β22+2 Cov(α,β)e-α1+e-β-e-β1+e-α1+e-β2
In the last two equations, Var denotes the variance and Cov denotes the covariance of the estimated parameters. These can be estimated as follows:
Varα=se(α)2
Varβ=se(β)2
Varτ=se(τ)2
Varα+β=Varτ=Varα+Varβ+2 Cov(α,β)
2 Covα,β=Varτ-Varα-Varβ
If the model with day effects and a group*day interaction fails to converge, then for each day, separate models are fitted of the form:
Logit Pbloodfed=logPbloodfedPnot bloodfed=μ+groupg
For each day the logits for the control group and treatment group are defined by
α=μ+group0,
β=μ+group1

SAS codes of simulations

   

Values of SubVar and DayVar that characterize the random animal effects and random day effects
In the simulations where the random animal effects and random day effects were randomly generated from Weibull distributions, SubVar = 1 and DayVar = 0.5 are used.  These values are selected based on results of simulations using the same SAS program "Evaluation techniques of data generations.sas".  The simulations were performed using different values of SubVar (0, 0.5, and 1.5) and different values of DayVar (0, 0.5, and 1).  The results show that the estimated proportions of blood-fed would be biased as the values of SubVar and DayVar increases.  SubVar = 1 and DayVar = 0.5 were selected since the estimated blood-fed proportions were close to the true values.  The variation of between animal was set as VarSub = 1 while VarDay = 0.5 because the variation between animals is probably greater than the variation between days in these environmental-control studies. 

The random animal effects and random day effects in the simulations were also randomly generated from normal distributions.   In order to have similar distance from the lowest values to the median values between Weibull and normal distributions, the SD_Sub and SD_Day were set as 1/3 of SubVar and SD_Day.  Therefore, SD_Sub = 0.33 and SD_Day = 0.166 were used in the simulations. Below is the Table that presents the 95% coverage of the distributions of the blood-fed arthropods between the animals or between the days.  For example, if the average proportion of proportions of blood-fed arthropods of the animals is 0.45, the 95% coverage of the distribution of true proportions of blood-fed arthropods of the animals is from 0.297 to 0.613.
