  Log:
  Regression.pm is a multivariate linear regression package.
  That is, it estimates the c coefficients for a line-fit of the type
  
        y= c(0)*x(0) + c(1)*x1 + c(2)*x2 + ... + c(k)*xk
  
  given a data set of N observations, each with k independent x variables
  and one y variable. Naturally, N must be greater than k---and preferably
  considerably greater. Any reasonable undergraduate statistics book will
  explain what a regression is. Most of the time, the user will provide a
  constant ('1') as x(0) for each observation in order to allow the
  regression package to fit an intercept.
