Hi,
I'm struggling trying to specify a multinomial logit discrete choice model
in R.
Any help and/or code examples appreciated.
I am specifically interested in specifying a model where no universal choice
set exists and each choice set has a variable number of alternatives (one of
which is chosen) see data below.
Many Thanks,
David
PS I have asked earlier but without reply.
Is it because:
a. it's a stupid question
b. It's obvious
c. No one knows the answer
Data:
> Chosen AttrQ AttrW | Choices set 1
> 0 8 0 |
> 1 20 34 |
> 0 7 2 |
>
> 0 5 3 | set 2
> 0 3 5 |
> 1 25 18 |
> 0 4 9 |
>
> 1 30 12 | set 3
> 0 2 4 |
