Welcome to Statalist, Ras!

  You apparently believe that the order in which you enter the predictors has some consequence. That is not so.  You only need a single model to assess the effect of each predictor, adjusting for the others: no looping required. To prove this to yourself, run both models and compare the coefficients.

Dear All,

I am new to Stata and having difficulty fitting a 
model. I have one dependent variable RECOVER coded 0 or 1. I also have 
10 independent categorical variables AGE, EDUCATION, RELIGION, MARITAL, 
SOC_CLASS, COUNTRY_BIRTH, EMPLOYMENT, YEARS_WORKED, NO_PARTNERS, and 
FAMILY_SIZE. I wish to model the effect of each sociodemographic 
variable on the dependent variable RECOVER whiles controlling for the 
remaining nine independent variables. First time round I wish to model 
the effect of AGE on RECOVER whiles controlling for the remaining nine 
variables as below. 


xi: logistic RECOVER i.AGE i.EDUCATION 
i.RELIGION i.MARITAL i.SOC_CLASS i.COUNTRY_BIRTH i.EMPLOYMENT 
i.YEARS_WORKED i.NO_PARTNERS i.FAMILY_SIZE

Second time round I 
will wish to model the effect of EDUCATION on RECOVER whiles controlling
for the remaining nine variables as below.

xi: logistic RECOVER i.EDUCATION i.RELIGION i.MARITAL i.SOC_CLASS 
i.COUNTRY_BIRTH i.EMPLOYMENT i.YEARS_WORKED i.NO_PARTNERS i.FAMILY_SIZE i.AGE 


My
question is instead of repeating the logistic command is it possible to
write one command maybe using looping that will let me avoid the 
repetition?

Ras
