I have done a research looking at different frequencies of abrasions (ablation, etc.) over time (in hrs) and my data mainly consists of zeros. As I am weak in statistics, I am unsure which statistics, if any, is appropriate for my data. Attached is an example of my data.
Originally, I had planned to do a regression analysis but I'm unsure if it will work, and all the other numbers that are not 0 were found to be outliers.
Will zero-inflation be an option?
