Creating Dummy Variable with large Number of Values

MAAbdullahAlMubarah

Dear Alteryx Experts 

 

I want to use linear regression for prediction, but I have a problem with the predictor variables (X-axis) 3 of them are categorical and I have at least 60 values on each of them , If I use formula tool for creating dummy variable I believe it will take more than 2 or 3 days to do so , can anyone tell me how to solve this issue faster? 

Note (If macro needed please provide it with workflow example for dummy creation for 60 values).

The same thing will happen even if I use R, I'm sure for that, I have experience with R, For Python, I think it will work but

I 'm not Python developer, can I get feedback from @jdunkerley79 and @BenMoss how to deal with this issue?

As you have done the work inside Alteryx, you shouldn't get the error from the linear regression anymore?

I didn't get your point?

Sorry, what I meant is that using the transpose and crosstab has pulled the work out of R and into Alteryx, so you shouldn't get the matrix error anymore?

There is no error from the dummy variables, I mean in the regression tool it cannot handle this large matrix of dummy variables created, It has a memory limitation problem.
