Biostatistics Seminar Series: Parameter interpretation in generalized mixed regression models
Non-linear link functions cause some difficulty in interpreting parameters in generalized mixed models. This presentation will cover the interpretation of both regression coefficients and variance components in generalized mixed models.
Regression coefficients for within- and between-cluster covariates have different interpretations that will be explained. Interpretation of variance components, within and between, will be covered.
The focus will be on logistic and log-linear models, although the ideas apply to other link functions. Numerical examples will be presented.

The NC TraCS Biostatistics Seminar Series provides more in-depth discussion of select biostatistical topics for clinical and translational researchers who have basic quantitative training in biostatistical methods. Join us this fall for seminars on power analysis & sample size planning, parameter interpretation in generalized mixed regression models, basic steps in questionnaire development, and choosing the right graphs and tables for your data.
