Hi everyone, How do I run Heckman models in R with two binary dependent variables? sampleSelection package in R works with standard heckman models ( binary DV for the selection equation and continuous DV for the outcome equation). In my case dependent variables are both binary (actually ordered but I didn?t find anything on that) So using sampleSelection package one could do this by running: SelectionEquation <- binaryDV1 ~ x1+x2+x3+x4 OutcomeEquation <- binaryDV2~o7+x1+x4+x5 HeckmanModel <- heckit(SelectionEquation,OutcomeEquation, data=mydata, method="2step") The problem is that heckit() doesn?t work here. I think in STATA one could use heckprob command for this. Anyone who knows more than me? Thanks!

The endogenous variable of the argument 'selection' must have exactly two levels (e.g. 'FALSE' and 'TRUE', or '0' and '1'). By default the levels are sorted in increasing order ('FALSE' is before 'TRUE', and '0' is before '1'). This also applies for the binary outcome equation. For continuous-oucome cases, the dependent variable(s) should be numeric.
seems to me that both equatio0ns can have binary values.
So using sampleSelection package one could do this by running: SelectionEquation <- binaryDV1 ~ x1+x2+x3+x4 OutcomeEquation <- binaryDV2~o7+x1+x4+x5 HeckmanModel <- heckit(SelectionEquation,OutcomeEquation, data=mydata, method="2step") The problem is that heckit() doesn?t work here.

What does it mean. Be more specific. And provide some data (preferably by dput). Or at least result of str(yourdata) to show that they are appropriate to the function. And do not post in HTML. Cheers Petr
use heckprob command for this. Anyone who knows more than me?

Dear Arne, Many thanks for this, It actually worked with heckit() command as well, do I need to use selection()? Also, I would be really grateful if you can suggest a package that would allow for estimation of heckman models with two ordered variables (0-1-2). Can sampleSelection handle this? Warm regards, Faradj

Dear Faradj

I suggest that you use the selection() command/function only. heckit() is just a wrapper to selection() with the only difference that heckit() estimates the model with the 2-step method by default, while selection() estimates the model by the maximum likelihood method by default (unless specified otherwise with argument "method"). I see no good reason for estimating the sample-selection model by the 2-step method instead of the maximum likelihood method.
Also, I would be really grateful if you can suggest a package that would allow for estimation of heckman models with two ordered variables (0-1-2). Can sampleSelection handle this?
Do you mean that the dependent variable of the selection equation is an ordered variable with three levels (0-1-2), that the dependent variable of the outcome equation is an ordered variable with three levels (0-1-2), or that both of the dependent variables are ordered variable with three levels (0-1-2) each? In any case: no, this is not implemented in the sampleSelection package. Sorry! Anyway, I guess that it is not too complicated to derive the likelihood function and implement the estimation yourself, e.g., using the maxLik package. If you do this, I would be happy to help you to implement this feature in the sampleSelection package. Best wishes, Arne
