I suppose what's confusing is that for the exponential, the mean is also the standard deviation. Holger: If you write the exponential PDF as exp(-x/mu) / mu, mu is the mean and the scale.

At least it is so for the gaussian. The scale corresponds to the variance.

It wouldn't be so bad if someone would do a page like the <a href="http://www.scipy.org/NumPy_for_Matlab_Users" rel="nofollow">NumPy for Matlab Users</a> page, but make it "SciPy for R and Matlab users". I would actually love to see someone do this. It'd be pinned up at my desk in no time and would no doubt save me from reading help() all day.
