PPT-ANALYSIS OF VARIANCE

In this Lecture we study whether changes in the independent variables cause changes in the mean response and we analyze the data using a method known as analysis of variance . When applied to generalized l inear models multilevel models and other extensions of classical regression ANOVA can be e xtended in two di64256erent directions First the Ftest can be used in an asymptotic or approximat e fashion to compare nested mo SPSS.
