scrap several more variates
do a fit? it is sketchy. and it still shows those damn lines.
fiddling with what variables to include

the fucking skewed lines are still there. whyyyy

this is sketchy.
i should be using grouped LASSO on the full dataset or something.
argh.

i should look at added variable plots to see if there's a single variable
 that is the cause of why the lines are there
