Hi @abhaylidbe. Thank you for your kind comments.
Unfortunately, the current version of xlogit does not support computation of marginal effects or elasticities. This is something I have in my to-do list, but I haven't had the chance to implement it yet.

Cristian,
Thanks for the reply. ME/Elasticities are very important for our work. I wish you can implement it soon. At least, is there a way to manually derive it once we have the model results? If so, would like to discuss it with you. LMK.

Hi @abhaylidbe, Sure. Let me think about a potential implementation timeline and I will let you know.

Dear Abhay, After estimating the effort involved in this implementation, I anticipate it would take at least a couple of months for completion given that my time is very limited right now. In case you know some Python programming and want to give this implementation a try, I would be happy to provide any necessary guidance on the internal functions inxlogit that you would need to modify.

Hello Cristian,
Hope you are doing well. I'm reaching out to you to check if you were able to add marginal effects/elasticities to XLOGIT. If not, can you please guide me in deriving the effects in Python.
Regards,

Hi @abhaylidbe,
I truly apologize for my delayed response. The margin effects/elasticities is a very desirable implementation for xlogit, but unfortunately time is a bit constrained right now, and I don't think I will be able to complete it in the nearby future. In case you want to give this implementation a shot and you are clear about the formulas and concepts involved, I could happily guide you with the Python programming part.
