Hi I am doing a simulation study as part of my PhD which inovles fitting an lm model, a gee model (via geeglm from geepack package) and a lme model (via the nlme package). After fitting the models i ideally would like to save the p-value of the beta coefficient, so that i can see how many were significant after running the simulation a number of times. However for all of these models i can only see a way of saving the coefficient value from the fitted models. On their own the coefficients are of no use to me. Does anybody know if it's possible to save standard errors of the coefficients or ideally the p-value of the cofficient? Many thanks Lucy
