..... Dear Statalisters:
If the interest is to run a linear regression of a
continuous variable as the response, say level of beta carothen, and for very small values the results are zero because the equipment can only show values equal or greater than .04, the use of -tobit- can be an statistical alternative? Let´s assume there is no money to buy a better device. Best regards, josé maria
