WebThis code provides (hopefully) useful code to extract goodness of fit statistics for log-linear models fitted via Poisson regression in R. Start with an arbitrary 5x5 contingency table and put it into dataframe format. Now, we fit a saturated model and a models of independence on these data. The next step in standard log-linear analyses is to ... Web10 apr. 2024 · The Akaike Information Criterion (commonly referred to simply as AIC) is a criterion for selecting among nested statistical or econometric models. The AIC is essentially an estimated measure of the quality of each of the available econometric models as they relate to one another for a certain set of data, making it an ideal method for …
