The results are not useable. Coefficients like that in a choice model indicate that there is something seriously wrong. You might start to find out if it is the RP specification by fitting an MNL without random parameters. Most likely, you probably have far too many random parameters in your model. A good tight specification should have only a small few RPs. /B.

The results are not useable. Coefficients like that in a choice model indicate that there is something seriously wrong. You might start to find out if it is the RP specification by fitting an MNL without random parameters. Most likely, you probably have far too many random parameters in your model. A good tight specification should have only a small few RPs. /B.
