Maybe you should first check out the -h fvvarlist- if you are a 11.1 user -
which we must assume as you have remained silent on your version...

Betreff: st: xi3 with char varname[omit] #

Hi all,

I am a very fresh user, probably i will be bothering u for a simple
thing, but couldnt find it on the archives and it is urgent.

I will apply logistic regression in STATA to backcheck my "odds ratio"
calculations from the LEM output. Therefore, I need to use effect
coding and set the same reference categories as I used in my excel
calculations. The following lines work fine separately, but I couldn't
combine them.Other than gender and satisfaction variables, I will be
using the default first category- so I  am not mentioning them.

char GENDER[omit] 2
xi3 e.GENDER

char SATISFACTION[omit] 3
xi3 e.SATISFACTION

xi3 e.DISCRIMN  e.ETHNICITY  e.PERCENT  e.ETHNICITY*e.PERCENT

 Any tips on how to combine them before I run separate logistic for
the two effect coded categories of the dependent variable DISCRIMN? My
trials mostly gave the error message  "characteristic
SATISFACTION[omit] (3 GENDER[omit] 2) invalid;variable SATISFACTION is
numeric"


Thank in advance!
