```Hi

Sorry for the vague explanations.

```
I want to check in how far being interested in a political scnadal and evaluating the scandal as an important problem, impacts the vote intentions of the people. My exampekl is the CDU- party finance scandal in Germany in 1999/2000.
```
My dependent variable is vote intention

1 = vote intention for CDU/CSU 0 = vote intention for other parties

Independent Variables:

subject orientation: 1 = interested in scandal 0 = not interested
problem orientation: 1 = scandal importatnt problem 0 = scandal not important

My logistic regression: logit voteUnion subject problem

```
My "not working" I mean that the Box-Tidwell test does not give any results. Normally below the regression, there would be columns with the results, yet in my case nothing
```

Iteration 0:  Deviance =  46385.51
Iteration 1:  Deviance =  46385.51 (change =         0)

[Total iterations: 0]

Box-Tidwell regression model

Logistic regression                               Number of obs   =      36278
LR chi2(2)      =     228.82
Prob > chi2     =     0.0000
Log likelihood = -23192.755                       Pseudo R2       =     0.0049
