in proc phreg, the results from "type 3 test " will change if i change the
coding method. (1 vs 0 or 1 vs 2) , i put the variable in class statement
already. ideally, it will be the same , as I consider as categorical data.
. the coding wont have impact...
(the analysis of MLE part will change as the coding change will leave to
main effect definition changes.. dont know why type 3 changes too.. )
anybody knows the reasons ?
Many thanks in advance ?
