49G 50G STAT3.8e.hp: Multiple linear regression & Restricted model

[Gil]

Just changed way of calculating VIF (Variance Inflation Factors) when multiple linear regression model is without intercept (same results now as with SAS or R statistical programs).

Besides that, the structure remains the same : probabilities, t, beta, covariances, (¹/²) (partial) correlations, test on beta's and on alternative model suppressing independent X variables, (adjusted) R2, multicolinearity (condition number), anova, Spearman’s coefficient and critical values, etc.

Explanations and examples still in the downloaded file and to be read only with the calculator as they were programs by themselves.

Commentaries welcome.

Gil
