Help using the zip functions for 10-fold CV ZIP elastic net model with random hyperparameter search #6

Closed delgaa07 closed 1 year ago

delgaa07 commented 1 year ago

I'm trying to use your function for a 10-fold CV ZIP elastic net model with a hyperparameter optimization using random search. I am having trouble with executing this desired strategy and would like to see if my use of the function is correct - I feel I am only performing a LASSO, hence the name of the object. Attached is a portion of my script that is supposed to cover this part of my analysis. I have been able to run the model so far but my alpha values are still stuck at 1. Another question I have is regarding the image below, is the mixture parameter being selected for actually '1' or am I not programming the function correctly?

This image illustrates what's currently inside the object once run.

Unfortunately, I am not allowed to share the data file b/c of HIPAA. However, I did provide a sample script with copy/pasted output from glimpse() of the de-identified dataframe. See the link below:

Any help with this would be appreciated - thank you for creating this function!
