st: dtobit Interpretation

[Abra Marie Jeffers <aj319@hermes.cam.ac.uk>]

Hello,

I am trying to interpret the output of -dtobit- for a continuous, level 
variable.

For example: 
If -dtobit- returns that the marginal effect at the mean of the 
probability of being uncensored is 0.002 for x1, can I say that "if x1 
increases by 10 from the mean, then the probability of being uncensored 
increases by 0.02 other things equal"?
Similarly, if -dtobit- returns that the marginal effects at the mean of 
the conditional expectation is -1.45 for x2, do I say that "if x2 
increases by 100 from the mean, then the conditional expectation 
decreases by $145"?

This seems too simple given the nonlinearities involved in the calculations.

I would really appreciate any suggestions on giving the decomposed 
marginal effects an economic interpretation.

Thanks,
Abra
