Most suitable regression model

[Tom Prosser]

Hello,
I have a dependent variable which is ranked from 0 to 1, continuous and left-skewed (see attached image). I have almost 1,000 observations. Which regression model might be best? Tobit? Someone else mentioned quasi-binominal, but this isn't on Stata. Any advice would be greatly appreciated,
Tom

Quasi-binomial [not binominal] is available through glm, link(logit) vce(robust) f(binomial) -- as discussed in (e.g.) http://www.stata-journal.com/article...article=st0147

See also betareg.

Thanks Nick - that's really useful :-)

Dear Nick, I typed glm, link(logit) vce(robust) f(binomial)into Stata but got 'last estimates not found'? If you have a minute, your thoughts would be greatly appreciated,
Tom

You do need to indicate the variables that the command should use. See help glm.

Thanks so much for your help! I'm looking at it now :-)
