Re: st: Tobit regression where left vs right censoring cannot be determined in the preferred dependent variable

I am attempting to perform a regression on a data set whose

dependent variable in the regression.
Look at -intreg- and see if it appears to meet your needs.
Say that I've got the number of persons living in poverty. As a raw
number, this is left censored at 100. Ideally, I want to look at
the percentage of the population that is living in poverty. So not
only do I fail to have a constant censoring value but, for a given
city with fewer than 100 persons living in poverty, I am not certain
if that city is left censored or right censored....
Do you have any idea how to handle this? Would it be all too
terrible to enter poverty = 100 when poverty (raw) <100, and simply
use OLS methods to analyze it?
