  • Initial values not feasible - Panel Data xttobit

    I am running a Tobit Model with panel data using xttobit in stata. I am getting the following errors message:
    initial values not feasible
    This problem does not appear when I run the simple tobit without xtoption. Any help to figure out this problem will be appreciated.

    Unfortunately there is no information in your post beyond your using xttobit and the error message. The following could be problems:

    1, Small sample size.

    2. Large number of predictors.

    3. Problematic distributions of any important variable.

    For us to get a sense of what might be wrong, the following might help:

    The exact command you typed. See http://www.statalist.org/forums/help#stata

    Basic summary statistics for the variables you used in the command.
