Re: [R] extracting the standard error in lrm

well, you can directly use the coef() and vcov() generics, e.g., library(rms) y <- rbinom(100, 1, 0.5) x <- runif(100, -3, 3) Fit <- lrm(y ~ x) Fit coef(Fit) sqrt(diag(vcov(Fit))) I hope it helps. Best, Dimitris On 8/11/2010 12:56 PM, david dav wrote: Hi, I would like to extract the coeffi
