Tīmeklis2014. gada 22. jūl. · 1 Answer. The problem is that glm.fit does not output of class glm, but a raw list with all kinds of data about the model. This cannot be fed to anova.glm since this function expects an object of class glm as produced by the glm function. If you have the raw data available (thus not turned in to a model matrix, you can apply … Tīmeklis2024. gada 15. nov. · For example, in our regression model we can observe the following values in the output for the null and residual deviance: Null deviance: 43.23 with df = 31. Residual deviance: 16.713 with df = 29. We can use these values to calculate the X2 statistic of the model: X2 = Null deviance – Residual deviance. X2 = … brainerd p44270w-sn-cTīmeklisAt this time statistical data were obtained by one-way ANOVA. The adjusted p-value and FDR values shown in this study are cited values of these statistical results. Additionally, as is well known, when the sample parameter is small or the number of iterations is small, the p-value tends to be large . brainerd p43935w-fb-c

TīmeklisThe p -values aren't actually computed until you run summary () on the model fit. By the way, use extractor functions rather than delve into objects if you can: fit$coefficients [2] should be coef (fit) [2] If there aren't extractor functions, str () is your friend.
