The classification/regression engine has found no solution.

Hi, Experts

When I run the regression modeler in SAP PA Desktop 3.0, I got the error message "

The classification/regression engine has found no solution."

Attachment is my sample data.

Hi, what the tool is saying here is that no model can be built from the data that was used. I suspect the reason for that is that your dataset is too small. Is it a possibility to get more data rows? Is this a regression problem or a time series problem (noticed a date...). Thanks & regards, Antoine

Hi, Antoine

After I get more data rows from 30 to 60, I can create the regression model.

Is there any data rows restriction of PA Automated regression model?

Thanks

Hi, Antoine

Y is my Target Variable, and X1~X20 is Explanatory Variables

Thanks for your reply.

Hi, what is the output variable that you are trying to model? Can you access to more input variables? Thanks & regards, Antoine
