Individual part-worth estimates #48

Dear John,

first of all, thanks a lot for this amazing package. I was wondering if there is the chance to extract individual part worths similar to the indpar from the mlogit package?

Thanks a lot

Thanks! You're certainly not the first to ask for this, so I'll probably need to include it at some point. This issue also mentions individual parameters (but in the context of prediction) and it includes most of the math needed to implement it. It's really just a matter of sitting down and writing the code - it's all been well-established with mixed logit for a long time. I just have other projects that are consuming more time. I'm also hoping someone else will come along and give it a shot themselves and post their code to make adding this feature a lot less work for me :). So, it will be done at some point, but I'm not sure when that will be. If I can get to it by the end of August then good, otherwise it'll probably wait a while once I start teaching again in the fall.

I see, thanks a lot for your detailed response. :-)
