Hello, I have a little problem with Mathematica's statistical distributions. These seem not to be evauluated properly. For example the documentation says that Variance[GammaDistribution[a,b]] should be evaluated to ab^2. In my worksheets I simply get: Variance[GammaDistribution[a,b]]. There are no errors or warnings whatsoever. Is there some package missing do I have to call the needs function in advance? Thanks.
