Course Spotlight
Our course spotlight is on two courses that deal with linear models:
The GLM course covers the derivation of the generalized linear model, starts off with the familiar case of linear regression with continuous responses (outcomes), and discusses how to handle over-dispersion in the data. In addition, you will learn how to
The HLM course extends the linear modeling structure to deal with the complexities introduced when data are clustered, repeated at the same time (repeated measures), or repeated sequentially over time (longitudinal). You will learn how to
Specify a linear mixed model
Identify the associated marginal model
Estimate the covariance and fixed effect parameters
Conduct hypothesis tests on models
Your instructor in both courses is James Hardin, Associate Dean of Faculty Affairs and Curriculum Professor at the University of South Carolina, and co-author (with Joseph Hilbe) of Generalized Estimating Equations.
