[m, v] = stdrstat (k, df) returns the mean and variance of the studentized range distribution for k groups and df degrees of freedom.

The size of m (mean) and v (variance) is the common size of the input arguments. A scalar input functions as a constant matrix of the same size as the other input. k must be an integer of at least 2 and df positive, Inf included; otherwise both are NaN. The mean exists only for df greater than 1 and the variance only for df greater than 2; where either does not, it is NaN. For df equal to Inf they are the mean and variance of the range of k standard normal variables.

MATLAB has no public counterpart of this function.
