How to deal with skewed distribution in GEE or GLM?

WebbFurther, it's common to fit a log-link with the gamma GLM (it's relatively more rare to use the natural link). What makes it slightly different from fitting a normal linear model to the logs of the data is that on the log scale the gamma is left skew to varying degrees while the normal (the log of a lognormal) is symmetric. WebbMay 9, 2012 at 18:03. @whuber If he says the response variable Y has a skewed distribution I guess there could be two reasons for it (1) The way he samples in the X space leads to the skewness in Y or (2) he samples in a way that would spread the Ys out but the residuals are highly skewed. In (1) the solution might be to sample more in regions ... terraform azure windows virtual machine https://bloomspa.net
