perl-Statistics-OLS

Perform ordinary least squares and associated statistics

I wrote Statistics::OLS to perform Ordinary Least Squares (linear curve fitting) on two dimensional data: y = a + bx. The other simple statistical module I found on CPAN (Statistics::Descriptive) is designed for univariate analysis. It accomodates OLS, but somewhat inflexibly and without rich bivariate statistics. Nevertheless, it might make sense to fold OLS into that module or a supermodule someday.

Statistics::OLS computes the estimated slope and intercept of the regression line, their T-statistics, R squared, standard error of the regression and the Durbin-Watson statistic. It can also return the residuals.
