Dear All, I have fitted generalized linear models with the glm() function from the package lme4. The statistical values it returns are the z-value and the p-value. Now I am searching for a way to get the F-values for my models to use for reporting - as to my knowledge
Your knowledge is insufficient. Your expectations are incorrect. Either consult someone locally who has sufficient statistical expertise or do some studying of GLM's. As this is a statistics not an R question, you might also wish to try posting to a statistics list instead, like stats.stackexchange.com. Cheers, Bert reporting z-values is not very useful and the F-values together with the p-values would be desired for the report. I tried the commands summary(model) , anova(model) noranova.glm(model), but couldnt get the F-values that way.
Is the command stat.anova(table, test = "F", scale, df.scale, n) the right choice? If yes, for this I need the 'residual mean square' to use as scale. But how to extract the 'residual mean square' out of my glm in R?
I am very thankful for your comments and advice!
