Chapters discuss:descriptive statistics using vector notation and the components of a simple regression model;the logic of sampling distributions and simple hypothesis testing;the basic operations of matrix algebra and the properties of the multiple regression model; testing compound hypotheses and the application of the regression model to the analyses of variance and covariance, andstructural equation models and influence statistics.
