Subject: proc phreg: type of variable is character with 4 values,
how to construct dummies?
Content-type: text/plain; charset=us-ascii
hi,
i use proc phreg and i have a variable of type character with 4 values.
non-numeric variable = group with the values A, B, C, D.
phreg wants to have numeric variables.
is there an easy way to construct the 3 dummies and why isn`t
proc phreg able to construct them automatically?
thanks,
stefan.
