Dear all, After running a glm, I use the summary ( ) function to extract its coefficients and related statistics for further use. Unfortunately, the screen only displays a small (last) part of the results. I tried to overcome the problem by creating/saving an object "coef" for coefficients of the model and export/save it e.g. as a cvs document. While I succed with this operatiion, I do not manage to pick the standard deviations and other statistics associated with individual coefficients. What may I do to get the whole set of coefficients and associated statistics for my GLM? Thanks for your help. J. Munyandorero [[alternative HTML version deleted]]
If I understand correctly.. using the example in ?glm > utils::data(anorexia, package="MASS") > anorex.1 <- glm(Postwt ~ Prewt + Treat + offset(Prewt), family = gaussian, data = anorexia) > summ <- summary(anorex.1) Then check > names(summ) for the available objects. For coefficients standard errors and t-tests > summ$coefficients Again do this for any object other than "coefficients" you would want from names(summ).

See this example: coef(summary(glm(Postwt ~ Prewt + Treat + offset(Prewt),family=gaussian, data=anorexia))) Is this you want?
