WebArguments. fml. A formula representing the relation to be estimated. For example: fml = z~x+y. To include fixed-effects, insert them in this formula using a pipe: e.g. fml = z~x+y fe_1+fe_2. You can combine two fixed-effects with ^: e.g. fml = z~x+y fe_1^fe_2, see details. You can also use variables with varying slopes using square brackets ...

Webspeedglm and speedglm.wfit fit GLMs to medium-large data sets, that is those storable into the R memory. The highest performances, in terms of computation time, are obtained when R is linked against an optimized BLAS, such as ATLAS. The function shglm is for a data set stored into a file of size greater than the available memory, and takes as argument a … WebAt least with the glm function in R, modeling count ~ x1 + x2 + offset(log(exposure)) with family=poisson(link='log') is equivalent to modeling I(count/exposure) ~ x1 + x2 with family=poisson(link='log') and weight=exposure.That is, normalize your count by exposure to get frequency, and model frequency with exposure as the weight. Your estimated …

WebRecords with analysis weight values that are less than or equal to 0 or are missing are not used in the analysis. Offset. The offset term is a "structural" predictor. Its coefficient is not estimated by the model but is assumed to have the value 1; thus, the values of the offset are simply added to the linear predictor of the target.
