I have two set of gamma distribution .
standard deviation is related to its population mean
Given unequal standard deviation, how do I make sure the population mean is equal (null hypothesis is TRUE) ?
Is the answer is we have to minus the population mean (alpha*beta) from the every sample we pick from simulation.? [ since i am care about mean and variance, then how can i do to maintain the populatio mean
If you care at all about variances being equal, you care about the scaling parameter. . In the general case, if you care about means, you care about scaling. [credited from post above]
