[R] p_values for GLMM

2007-03-27 Thread Cristina Gomes
Dear R-users, I was wondering if anybody knows if it's possible to obtain a p value for the full model of a GLMM with the lme4 package. I was told that I should check whether the full model including all the predictor variables is significant before doing stepwise regression or further analysis,

[R] p-values for GLMMs

2007-03-23 Thread Cristina Gomes
Hi there, I have a question about the GLMM that I'm doing, that a statistician friend suggested I should have for my analysis. I would like to know if there's any way of obtaining a p value and R square for the full model (and not each variable separately) as to asses whether this model is

[R] GLMM plots

2007-03-13 Thread Cristina Gomes
Hi R-users, I would like to plot the effects of one of the predictor variables on the response variable in the GLMM I ran with the lme4 package. Usually when doing a multivariate analysis I would obtain the residuals of the model without the predictor variable of interest (x1) and then plot

[R] Appropriate error distribution

2007-03-07 Thread Cristina Gomes
Hi, My name is Cristina. I'm interested in studying which continuos predictor variables (such as grooming received, rank, etc.) affect grooming given, as well a continuos variable. I'm having problems finding an appropriate family distribution to fit the GLMM I'm doing. The response variable,

2007-03-06 Thread Cristina Gomes
Hi all, I was wondering if somebody could give me advice regarding the dispersion parameter in GLMM's. I'm a beginner in R and basically in GLMM's. I've ran a GLMM with a poisson family and got really nice results that conform with theory, as well with results that I've obtained previously
