      The kurtosis of Student’s t is infinite when df ≤ 4. Otherwise it is 6/(df – 4) The skewness of Student t is 0, unless df ≤ 3, in which case it is not defined. The standard deviation of Student’s t distribution is the square root of df / (df – 2), unless df ≤ 2, in which case it is not defined.
