It appears that the heckit $probit object is of class 'glm' and so, for
example:
main.result - heckit(whateveryouaredoing)# Do your heckit()...
probit.result - main.result$probit # The
As I read it hectik() in micEcon does not fit by maximum likelihood, so
AIC is undefined. (People seem to have a magic faith in AIC as a
universal panacea, but it does come with a long list of conditions for
applicability.)
heckit's $probit is apparently only part of the fitting, but for any
Hi,
I have used the heckit function in micEcon. Now I
would like to evaluate the fit of the probit part of
the model but when I enter
AIC(sk$probit)
I get this error
Error in logLik(object) : no applicable method for

How can I then get the AIC for this model?
