My dependent variable is interval but bounded in the interval 5 to 80. All the values are known within the accuracy of the experiment and it is not possible for values to occur outside of these bounds. I had intended to analyse the data within a regression framework but I am uncertain which regression model to use.
Would tobit or truncreg be appropriate or is there another model; or is the fact that the data does not follow the OLS assumption of an unbounded dependent variable not that important?
