It looks accurate. :) Also it mentions that ddof=0 gives the ML estimate, which is often overlooked. A warning about what ddof=1 may/will do to the standard error of the variance would also be useful. Estimating the variance unbiased can be equivalent of throwing away a substantial portion of the data; which in turn may translate to a lot of lost investment in work and money. Sturla Molden
