described in [XT] xt, we fit a random-effects tobit model of adjusted (log) wages. We use the ul() option to impose an upper limit on the recorded log of wages. We use the intpoints(25) option to increase the number of integrationpointsto25 from12,which aidsconvergenceofthis model....

The Tobit model's capability to address the skewness in the dependent variable's distribution is noteworthy. This feature makes it particularly suitable for scenarios where the dependent variable's values are not fully observable, providing a more accurate representation of the underlying ...
