    Generalised linear models or GEE?

    I am working with choice test data from an Ecological experiment and I need to decide if I am doing a GLM or GEE. I am running SPSS but also not sure about data input with these tests, I haven't performed either of them before. Data was gathered from multiple subjects at different time points...

    Link = log code won't work

    Hi, doing a generalised linear model with poisson distribution, here is my model code... model<-glm(carnivore_abundance~altitude_1+dist_stream+canopy_openess+basal_area+dist_large_river,family=poisson,data=main_data) really frustratingly whenever I try to add link=log is doesn't work it...

    General and generalised linear models

    Hi, I've done a few GLM's with poisson distribution, the code I've used is name<-glm(dependentvariable~independent+independent+independent,family=poisson,data=datset) for some the dependent variable is non-normally distributed so I believe I need to use a generalised linear model. But...

    How does OLS regression related to generalise linear modelling

    Hi, I need to understand how OLS regression relates to generalise linear modelling. Does the relationship only exist when the assumptions of OLS regression can not be met i.e. the relationship between the dependent and independent variables is not linear, the regressor variables are not...

    Weight Matrix in Generalised Linear Models

    Hi, I was wondering if I am trying to do IRLS for GLZ. Is there a way to compute the weight matrix directly for the data I have? I think its possible if the data is normally distributed , what about if the data is non-normal Thanks
