The library contains the following modules. Many of them are derived from the examples in the IML sample library. Each module is described in detail at the end of this chapter.

COLVEC

converts a matrix into a column vector

CORR

computes correlation coefficients

EXPMATRIX

computes the exponential of a matrix

GBXWHSKR

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

generates a random sample from a multivariate normal distribution

RANDWISHART

generates a random sample from a Wishart distribution

REGRESS

performs regression analysis

ROWVEC

converts a matrix into a row vector

RSUBSTR

replaces substrings

STANDARD

standardizes numeric data

TABPRT

prints matrices in tabular format
