Downside variance 1.0

Y = DOWNSIDEVARIANCE(Y) returns the downside variance for columns of variable Y.Y = DOWNSIDEVARIANCE(Y, m) returns the downside variance using vector m as expected value for columns of variable Y.===================================================Downside variance is defined as the average sum of squared negative differences between each observation of a variable and a parameter m: E[min(y - m, 0) ^ 2]If omitted, m is the sampe mean of Y.===================================================See also VAR, STD, COV.
