Problematic Observations, desirable but not required; the second refers to properties that are required when ordinary least squares (OLS) estimation is used to find a least squares solution; and the final category refers to properties that are required for all methods of linear estimation.

Categorical Predictors,ons (Democrat, Republican, Libertarian), or an experimental treatment (control group vs. experimental group). Historically, analysis of variance (ANOVA) was used to analyze data with categorical predictors, but multiple regression can be used as well.

Multiple Regression,he phenomena they study, scientists use multiple regression to examine the association among several predictors and a criterion. In this chapter, you will learn how to perform multiple regression analysis using tools you mastered in previous chapters.

Matrix Decompositions, matrix decompositions. There are many varieties, but all decompose a matrix into two or more smaller matrices. Their value is twofold: they highlight variables that share common variance, and they offer computationally efficient ways of solving linear equations and performing least squares estimation.
