Excess kurtosis (0 for the normal distribution).
Mean (NaN when it does not exist, Infinity when it is infinite).
Median: the q function at 0.5 (for discrete distributions the smallest x with F(x) >= 0.5).
Mode: the maximum of the density (NaN when it is not unique; the larger of two adjacent modes).
Standard deviation, the square root of the variance.
Skewness, E[(X - mean)^3] / sd^3.
Variance (NaN when it does not exist, Infinity when it is infinite).
