Anаlysis оf Vаriаnce A regressiоn mоdel included 4 variables (Full). The analyst is trying to decide if the model is statistically significant using only 2 variables (Reduced). Using the output from the ANOVA, calculate the F-statistic that would be used to determine significance of the difference between the two models. ANOVA for all Variables (Full) Source DF SS MS Regression 4 4814.3 1203.575 Error 10 3527.4 352.7 Total 14 8341.7 Analysis of Variance (2 variables-Reduced) Source DF SS MS F-Value P-Value Regression 2 3653 1826.5 Error 12 5689 474.08 Total 14 9342 Once you have determined the F-statistic, comment on why this value is important in regression models.
