Suppose that I have a logistic regression with continues independent variables a,b,c. In my logistic regression, c is equals to a/b. Is this true to have variable c in logistic regression? These independent variables are financial rations. Output of logistic regression using SPSS:
EXP (coef)
a 4.937568
b 1223.406
c 0.30749
Is this conclusion true? : EXP(coef) value of c is lower than 1 (negative effect on dependent variable-odd ratio) because EXP(coef) value for b is higher than a. (all coefficients are statistically significant at 5%)
Dear Erm
Yes, It's true as you have calculated the coefficient for logistric regression which (coef) depends on variable. It's not matter what you have find.
So because of extremely high "EXP(coef)" value for "a" comparing to "b" we have lower than "1" value for "c"?
