Consider a variable that can take both negative and positive values, and that has the following density plot:
I am trying to identify the distribution of this variable. The density plot resembles that of a Gamma distribution. However, since the variable can take negative values, it certainly does not follow a Gamma distribution.
What is the best guess as to the distribution of this variable? Of course, the next step would be to plot a QQ plot of the sample quantiles v.s. the theoretical quantiles of the "guessed" distribution.
Any help would be appreciated. Thank you!
