Loop for Tobit

[Olive Bat]

can some tell me how to write a loop for tobit...

[Marcos Almeida]

Which loop, I mean, what commands you wish to apply?

[Olive Bat]

foreach x of varlist a b c d e f d e f g h{
tobit `x' y,ll(0)
mfx compute,predict (e(0,.))
}

[Olive Bat]

is this correct..

[Marcos Almeida]

To start, the legal command is - tobit y x - not the opposite

[Olive Bat]

i want t o write a tobit regression and thus wanna form a loop.. using foreach

[Olive Bat]

after running the tobit and computing below mfx
mfx compute,predict (ystar(0,.))

it says
warning: predict() expression ystar(0,.) unsuitable for standard-error calculation;
option nose imposed
why so?

[Marcos Almeida]

Please read this text, particularly #4

[Marcos Almeida]

I do not use - mfx - command. That said, adding "." will skyrocket the upper limit for right censoring.

Thanks Marcos will look into it.
