Because there are many 0s in my predictors, they are heavily skewed to the right.

1. Do I need to transform my predictors? (I know that when the DV is a proportion, you would use logit transformations, etc.)

2. I've tried sqrt, fourth sqrt, arcsin, and log (with adding a constant to deal with 0s) but it doesn't seem to help the shape of the distribution. What to do next?

Thanks in advance for your help!
