Logistic Regression Prediction Equation

Logistic Regression Prediction Equation
 
|
I’ve done a logistic regression using a number of continuous (interval) predictor variables and some categorical predictor variables and now have my model. Is there something
in SPSS that will allow me to apply the resulting ‘regression’ coefficients to new data and create an equation for use in predicting membership in the dependent variable? If not, what is it that I need to do to create this prediction equation? Jerry Weinberg, Ph.D St. Thomas University |

Save your model as pmml (xml) when
you estimate it, and the use Utilities > Scoring Wizard to generate
new predicted values. You can paste the syntax generated by the
scoring wizard for reuse. It will include a MODEL HANDLE command
to select the pmml file and COMPUTE commands using the APPLYMODEL function
for the calculations. If there are transformations needed for the
new data, they be part of the pmml (see the TMS command), or they
could just be repeated with regular syntax before doing the predictions.

Hi Jon,
Is the scoring wizard only available in latest version of SPSS? I have version 20.0.1 but could not find this option. Mike =====================
