### Why can a model's SHAP values change on a new dataset?

Why can a model's SHAP values change on a new dataset? WHY SHOULDN'T THEY? When you calculate a mean on a new data set, you expect to get a slightly (or radically) different value. When you calculate ...
The answer is NO. To reformulate the question: Given any two univariate distributions $F, G$ (represented with their cumulative distribution functions) is there always a bivariate distribution with $... 4 votes Accepted ### Does this type of distribution have a name?
