Comments

The test enables you to determine the statistical significance of a subset of regression factors. It checks the hypothesis on the number coefficients equality to zero for the specified subset of factors.

The function returns Fisher statistics, chi-square statistics and the appropriate probability values. If the probability value is less than 0.05, the null hypothesis is rejected at 5% significance level. If the hypothesis is not rejected, the selected factors can be removed from the regression equation.

All characteristics associated with regression (modeling series, residuals, model coefficients) are calculated for a model without redundant regressors.
