Why does the sample size shown on the Model tab of the SLRM node nugget not equal the size of my training data?

Technote (FAQ)


Question

In SPSS Modeler, if you run an SLRM node, on the Model tab of the output nugget you see a chart on the left that shows Model Performance. The sample size for the training data is given on the horizontal axis of the chart. The value(s) given are smaller than the size of my training data. Why is this?

Answer

There is a drop-down list that lets you select which offer is to be viewed. Each offer is being handled separately. The sample size for the training data for each offer is what's being shown on the chart. These should sum to your training data size across all offers.
