PCA also need X variables which have numeric value,better continuous value .
The problem is how you get these X variables.

I'm sorry! I meant to attach some example code. Thank you for sharing that link. That is really helpful. Here is some example code. For Fx_claim and Trauma_claim, 0=no claim and 1=1 claim. Patient 1 has 2 fragility fractures (Fx_claim=1 and Trauma_claim=0 for the same day) and 1 non-fragility fracture (Fx_claim=1 and Trauma_claim=1 for same day); Patient 2 has a non-fragility fracture (Fx_claim=1 and Trauma_claim=1 for the same day); Patient 3 has no fracture or trauma code (both=0). patid fst_dt Fx_claim Trauma_claim 1 2016-01-01 0 0 1 2016-02-03 1 0 1 2016-02-05 0 0 1 2016-12-01 0 0 1 2016-07-05 1 0 1 2016-07-17 1 1 1 2016-09-02 0 0 2 2016-02-04 0 0 2 2016-05-21 1 1 2 2016-10-25 0 0 2 2016-11-11 0 0 3 2016-02-19 0 0 3 2016-04-26 0 0 3 2016-04-28 0 0 3 2016-06-12 0 0

This works great! However, this results in a single line for each patid. This is fine, because I then merged this dataset with my other dataset in the long format, and the group variable populated correctly. This is awesome! Thanks so much!

Thank you very much for this! You are correct, my current code is taking up so much disk space and usually up to a day to run. This will be extremely helpful!
