WeibullCompare

Compares two sets of data from Weibull distributions

Given independent data sets x and y, fits a two-parameter Weibull model to each set, then estimates the difference in mean or median (y - x) between the two sets with a specified confidence interval. Also returns a p-value, the probability of a difference as large as that observed, assuming that the means/medians are equal. Uses approximations that may be inaccurate for small sample sizes.
