draws a box-and-whiskers plot

GPROBCNT


draws probability contours for - data

GXYPLOT


draws scatter plots of - data

MEDIAN


returns the median of numeric data

QUADREG


performs quadratic regression

QUARTILE


computes quartiles

RANDDIRICHLET


generates a random sample from a Dirichlet distribution

RANDMULTINOMIAL


generates a random sample from a multinomial distribution

RANDMVT


generates a random sample from a multivariate Student’s distribution

RANDNORMAL
