I have a distribution (of a dependent variable) like below. I have five independent variables. I want to fit an equation using regression. Which regression model I should choose? Or how should I choose a regression model? enter image description here

  • This really isn't sufficient information to permit focused answers. "How to choose a regression model" is a huge subject that is too broad to be addressed here. The distribution of the dependent variable has little bearing on the choice of the model. Have you searched our site for ideas yet? – whuber Dec 06 '15 at 15:22

There are parametric regression models that may fit. Elsewhere on this site is discussed ordinal regression, which is a semi-parametric model that has to fit the distribution of $Y$ for a given $X$ because it makes no distributional assumptions for any one set of $X$.

See for example Which model should I use to fit my data ? ordinal and non-ordinal, not normal and not homoscedastic
