Design of Experiments project includes functions dedicated to model building. In the already existing relevant functions, I added doetbx_least_squares.sci and doetbx_rsquared.sci.

The first macro computes the slope and intercept of a linear model, using backslash operator and the latter computes the coefficient of determination R2. I committed both of them in Scidoe repo. Next step is to test these functions for accuracy and speed, using datasets provided by NIST.

Further investigation is needed for doe_yates.sci and builder.sce.

In doe_yates.sci, I replaced sortrows() function with gsort, but I get error when I call for sorting the effects [ef,id] = doe_yates(y,%T), while builder.sce presents control instruction error when executing.
