SPSS logistic regression
I'm wondering if there is a way to get many single covariate logistic regression. I want to do it for all my variables because of the missing values. I wanted to have a multiple logistic regression but I have too many missing values. I don't want to compute a logistic regression for each variable in my DB, is there any automatic way?
Thank you very much!
You can code it using SPSS syntax.
LOGISTIC REGRESSION VARIABLES F2B16C -- Dependent variable /METHOD=BSTEP -- Backwards step - all variables in then see what could be backed out XRACE BYSES2 BYTXMSTD F1RGPP2 F1STEXP XHiMath -- Independent variables /contrast (xrace)=indicator(6) -- creates the dummy variables with #6 as the base case /contrast (F1Rgpp2)=indicator(6) /contrast (f1stexp)=indicator(6) /contrast (XHiMath)=indicator(5) /PRINT=GOODFIT CORR ITER(1) /CRITERIA=PIN(0.05) POUT(0.10) ITERATE(20) CUT(0.5).`
If you do that you can also tell it to keep records with missing values where appropriate. add /MISSING=INCLUDE
If anyone knows of a good explanation of the implications of including the missing values, I'd love to hear it.
