[R] How to extract p value from the lmekin object obtained by fitting mixed model with function lmekin() in package coxme?
Hi, R experts I am currently using lmekin() function in coxme package to fit a mixed effect model for family based genetic data. How can I extract the p value from a lmekin object? When I print the object in R console, I can see the p value and Z value are just over there. But I can not extract them by the coef() function. kinfit$coefficient$fixed (kinfit is the name of the lmekin object) just include the intercept and the value of fixed effects. Where are p and Z values? Thank you! -- Tianxiao "Joshua" Zhang, Ph.D. student Human and Statistical Genetics Program Division of Biology and Biomedical Sciences Washington University in St. Louis [[alternative HTML version deleted]]

Perhaps what you want to explore is the object returned from the summary method rather than the fit object? coef(summary(kinfit)) --------------------------------------------------------------------------- Jeff Newmiller The ..... .....
