Dear all,
From some graphs and some numerical tests, I have showed that my data is not normally distributed. I can check if the distribution of my data looks like a Weibull distribution, exponential distribution, lognormal distribution, for instance. However, I was wondering: why do I want to know the distribution of my data? Do I need to know it for estimating and testing slope coefficients? Or is there another reason why I should know it.
The reason why I am asking is that my supervisor asks for an empirical distribution of my dependent variable in a regression model. But I just wanted to know why?
Thank you,
Best regards
