Predictive analysis and linear regression

Question

Hello Community! Hope you all are well! I am having some issues with predictive analytics which involves linear regression and Pearson correlation.

The issue:

I have this data set which includes stores and a bunch of other variables related to the store.

I am trying to do a Pearson correlation but when i get the data from that and use it on linear regression, I get a bunch of errors.

I have tried Pearson correlation, and association analysis but nothing is working.

Could anyone help me out on what to do?

Hi @newalteryxuser435 ,

as @IraWatt already replied, it would be helpful to have at least a screenshot of the error message. In addition - could you provide more detail on the data/the problem? Sample data would help get a better impression what's causing the problem.

As a best guess - a lot of errors using predictive tools are caused by NULL values in the data, so a "quality check" might help.

Best,

Roland
