gpstat
              Compute statistics of the generalized Pareto distribution.
 [m, v] = gpstat (k, sigma, mu)
 returns the mean and variance of the generalized Pareto distribution with
 shape parameter k, scale parameter sigma, and location parameter
 mu.
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 inputs.
 When k = 0 and mu = 0, the generalized Pareto
 distribution is equivalent to the exponential distribution.  When
 k > 0 and mu = sigma / k,
 the generalized Pareto distribution is equivalent to the Pareto distribution.
 The mean of the generalized Pareto distribution is not finite when
 k >= 1, and the variance is not finite when
 k >= 1/2.  When k >= 0, the generalized
 Pareto distribution has positive density for x > mu,
 or, when k < 0, for
 0 <= (x -  mu) / sigma <= -1 / k.
