20 Notes: All distribution options were used in the first round search. The above probability plot has only two panels, as they were deem more suitable than others in the second round search for the data distribution fit. Ideally, P

-value for a selected fit would be 0.05 or higher. When that isnot possible, we would look at if the data points (in red) are close visually to the fit line (middle, blue line; the other two lines form the 95% confidence interval for a given x value), especially for > 50% on the vertical axis (which corresponds to cells O18:P33. Among the data distribution options available in Minitab 16, only five of them (Normal, Exponential, Lognormal,Gamma, and Weibull) are facilitated in Excel with a

veryuseful distribution function. That is to say that we have to trust the value in cell P31,1.28ton/day of SO2, as the 99 percentile value of the 30

-day rolling average, as we have an Excel distribution function to check its validity. (HJ, 12/15/2012)30
40 Although Minitab 16 data are handy (cells O37:P67), for the Normal fit, we can also 50 calculate the percentile value in Excel, for the given L4 SO2 data. 60
