stepwise method on command line or program
Posted: Sat Apr 21, 2012 12:45 pm
I have tried the following
equation eq89lcomb10.stepls(method = "comb" nvars=4 force prompt ) log(obese) c @ afram doc educ fit fruit gdp homeown income nohealth phys pov unemp veg log(afram) fruit^2 income^2 veg^2
and eq89lcomb10 is always forward stepwise. I have also tried
equation eq89lcomb10.stepls(method = "back" nvars=4 force prompt ) log(obese) c @ afram doc educ fit fruit gdp homeown income nohealth phys pov unemp veg log(afram) fruit^2 income^2 veg^2
and get the same forward result.
I have tried
equation eq89lcomb10.stepls(method = "combinatorial" nvars=4 force prompt ) log(obese) c @ afram doc educ fit fruit gdp homeown income nohealth phys pov unemp veg log(afram) fruit^2 income^2 veg^2
and get the same forward result.
