Hi, while working on MATH-753, I found that some methods o.a.c.m3.distribution.GammaDistribution were ill-named. Indeed, the class javadoc explicitly refers to the Wikipedia page. In this page, the shape parameter is named alpha and the scale parameter is 1 / beta (inverse of beta), while in the current implementation, the shape parameter is named alpha, and the scale parameter is named beta (not 1 / beta !!!). This might be confusing. Looking at other web pages, I see there is apparently no consensus on the naming of shape and scale parameters. The problem lies with the accessors, which are double getAlpha() double getBeta()
I think these accessors can lead to confusion. I would therefore propose to deprecate them, and replace them with double getShape() double getScale() What do you think ?
