Obtaining p-values for coefficients from LRM function (package Design) - plaintext

Sent this mail in rich text format before. Excuse me for this. ------------------------ Dear all, I'm using the lrm function from the package "Design", and I want to extract the p-values from the results of that function. Given an lrm object constructed as follows : fit <- lrm(Y~(X1+X2+X3+X4+X5+X6+X7)^2, data=dataset) I need the p-values for the coefficients printed by calling "fit".
The individual p-values are not very meaningful. anova(fit) returns a matrix of meaningful tests with P-values. Frank
fit$coef (gives a list of only the coefficients) fit$pval, fit$p, fit$pvalue, fit$p.value,... : nothing works str(fit) : no hints there fit[1,4] : gives dimension errors help files don't seem to give me a function that extracts them. Yet, they are calculated and printed, based on the Wald statistics. So they must be reachable. Anybody knows how? Thank you in advance Kind regards Joris
