Hello Members,

After searching online and SPSS manual, I am not reaching you to you experts.

Data: 2-year historical monthly data with following variables:
1. Overall satisfaction (1-5 scale)
2. Performance on attributes - speed of service, menu, staff etc. (1-5 scale)
3. Type of order - Take out, dine-in, delivery (nominal)

Issue: Satisfaction score has been declining since last 6 months (trend inconsistent with previous year). Need to identify drivers of DISatisfaction and whether type of order play role in this.

Approach:

1. I tried Time series forecasting expert modeler to determine signficant predictor but it does not help as it it meant more for drivers of satisfaction than DISatisfaction and plus it does not handle nominal predictors.

Question: Does spss have any function that can help me to achieve my objective?

Mike
