Use a square root transformation. Binomial Distribution Number of successes in n independent trials. Use the arcsine or angular transformation. Using estimates of the standard deviation and mean from the data, estimate the slope, b . The value of p for a variance stabilizing transformation is 1- b .
Logarithmic transformation is used with positive integers which cover a wide range.
Useful when the standard deviations are proportional to the means. Checking assumptions, deciding on corrective action, checking assumptions again. 105 obs hidden. 74 obs hidden.
