BMTRY 711 : Analysis of Categorical Data

DESCRIPTION

This course offers a short review of standard chi-square methods, followed by several special-purpose two-dimensional techniques. Other areas covered include log-linear models, analysis of threedimensional and higher tables, model selection strategies, maximum likelihood and weighted least squares methodologies, logit models, diagnostics, GEE, patterned tables, and treatment of zero cells.
