Linear Regression Results

[maiacooper]

I am doing a linear regression model and when I put in my variables eg. region, household type, category, subcategory ... etc. the majority work well and tell me the significance but for some variables, usually region it will just say NA for the results. This does not always happen though it is dependent on the variables I choose but I want to be able to select them all to do a comparison.  

Do you know why this is happening or how I can avoid getting NA?

Hi @maiacooper, could you explain a bit more as to what you are trying to achieve? 

In addition, have you checked your data types for each of your fields? Sometimes they may be coded wrongly, and that can impact results. 

Oh, if you're comfortable enough to share the data and the workflow, could you kindly export the Alteryx workflow here for us to help take a look?
