Hi,

Been running the lrm model from the Design package. (Thanks Frank!)

There are some output columns that I don't quite understand.

What is "Wald Z" and then "P" which is 0 for all rows???

-----------------------------------------------
                Coef   S.E.   Wald Z P
Intercept -2.797 0.0431 -64.90 0
val1          3.003 0.1347  22.30 0
val2          4.882 0.1632  29.91 0
-----------------------------------------------

Thanks!!!
