Glm correlated variables
WebGEE estimates are the same as Ordinary Least Squares (OLS) if the dependent variable is normally distributed and no correlation within responses are assumed. Variables. The response variable (Y) can be either categorical or continuous. Yij represents the response for each subject, i, measured at different time points (j=1,2,…,ni). WebThe philosophy of GEE is to treat the covariance structure as a nuisance. An alternative to GEE is the class of generalized linear mixed models (GLMM). These are fully parametric and model the within-subject covariance structure more explicitly. GLMM is a further extension of GLMs that permits random effects as well as fixed effects in the ...

WebDec 15, 2024 · 7. In general, it is recommended to avoid having correlated features in your dataset. Indeed, a group of highly correlated features will not bring additional information (or just very few), but will increase the complexity of the algorithm, thus increasing the risk of errors. Depending on the features and the model, correlated features might ... WebOct 27, 2024 · Can Generalized Linear Models have correlated data?
