Hi there

Im trying to apply some data to a multiple regression model. The issue i am having is that some of the variables are binary responses, and some are categorical, can any one please help me with how to get it into a form where i can apply straight into a multiple linear regression model, heres a few rows of the data:


DOB NKID DEP PHON SINC AES DAINC RES
19.0 4.0 .0 1 .00 R .00 O
41.0 2.0 .0 1 .00 P 36000.00 O
66.0 .0 .0 1 .00 N 30000.00 N
51.0 2.0 .0 1 .00 P 464.00 O
65.0 .0 .0 1 .00 P 15000.00 P






Where Phon is the binary respone, and AES and RES are categorical responses.

Many Thanks
