[R] log-linear analysis - calculate treatment effects

2006-01-17 Thread Becker Cordula
Dear all, I have run a hierarchical log-linear analysis using loglin {stats} and came up with a specific model. loglin returns me the parameter estimates giving me an idea in which direction the observed frequencies deviate from the expected ones for my different factors. To assess the
