I have ignored so far (uniformly most powerful) UMP tests for equivalence and only implemented TOST. I finally think that we should add them for some easier cases. Add new...

I finally found inference for skew and kurtosis for nonnormal distributions Bao 2013 looks good Pewsey 2005 seems to be the first to derive the distribution for kurtosis Mahmoudi et...

no idea what this means, I'm not familiar with the details of the code qsturng is used for the distribution of tukeyhsd statistic I was semi-randomly trying out numbers in...

(mainly to park a reference for now) We have quantile based measures for skew and kurtosis (relative to normal distribution) Here is an article that includes confidence intervals and references...

There is a large list of one to k sample tests on variances, and covariances. IIRC then they are all missing except for Levene and Bartlett in scipy.stats. Do we...

We don't have much specifically for checking tail behavior of distributions. Would be useful to check whether we might run into estimation problems because of observations with large deviations because...

just a reminder issue (I don't have the references right now) Bartlett variance test can be improved for non-normal distributions by taking kurtosis into account. One of the monte carlo...

"Never use Fisher's exact test !" follow-up to #2605 confidence intervals for two sample proportions unconditional exact tests guarantee the size (less or equal to nominal size) but are more...

part of oneway methods are tests for equality of scale using oneway anova methods, Levene, Brown-Forsythe and variants. We don't have much explicitly for the 2 sample case. In this...

a reminder for now Whenever I look for something in proportions.py, I'm getting a bit confused what cases the different functions include. I wrote it a long time ago mostly...
