# How to regress a positive response variable that is also not a count variable?

I am asked to perform a regression on a dependent variable that only takes positive values. Intuitively one can think of Poisson or negative binomial, but unfortunately the response variable that I am dealing with is not a count variable. How can I perform a regression on such response variable? any ideas?

• GLMs can deal with right skew continuous distributions; there's the gamma and the inverse Gaussian - indeed the whole Tweedie family, indexed by $p$, the power in the variance function; these are continuous for $p>1$. There are other alternatives to GLMs of course, but that's where I'd start. – Glen_b Dec 13 '13 at 0:43
