Description: A standard normal distribution is a normal distribution with zero mean (mu=0) and unit variance (sigma^2=1), given by the probability density function and distribution function P(x) = 1/(sqrt(2pi))e^(-x^2/2) (1) D(x) = 1/2[erf(x/(sqrt(2)))+1] (2) over the domain x in (-infty,infty). It has mean, variance, skewness, and kurtosis excess given by mu = 0 (3) sigma^2 = 1 (4) gamma_1 = 0 (5) gamma_2 = 0. (6) The first quartile of the standard normal distribution occurs when D(x)=1/4,...
