The SDL Component Suite is an industry leading collection of components supporting scientific and engineering computing. Please visit the SDL Web site for more information....


The unit SDL_statis offers some of the most fundamental procedures of mathematical statistics. Along with the Gamma and the Beta function, all major types of distributions are implemented (normal, t, F, and chi-square distribution). A major benefit of this package is that the distribution functions are calculated analytically and not by approximations, or by table lookup. Thus the precision is at least 8 digits. In addition, many of the functions of the statistical package of Microsofts Excel® correspond to the SDL routines.

Further, the package contains a component to generate random numbers of arbitrary distributions, a component for performing cross validation, and a component to establish a partial least squares model.
