I have a dependent variable, days.to.event, that looks almost bimodal at 0 and 30.
I understand that there is no transformation that can normalize this. In fact, when I fit a linear model (lm) with a single predictor, I get the following residual plot. No transformation of DV or IV seems to help. How do I go about addressing this issue?
Please note that the dependent variable is not censored.
[0,30]
. Are these days of the month? What kind of event are we talking about? $\endgroup$
