It appears that matlab mnrfit function automatically omits
the constant term when ordinal data is chosen.

I was trying to use mnrfit for my problem but I am getting
the following error:

====ERROR====
??? Error using ===> mnrfit
Inputs to mnrfit must be floats, namely single or double.

Error in ==> mnrfit at 125
dataClass = superiorfloat(x,y);
====ERROR====

My variable x is double. I tried casting it as single using
x=single(x); command, Still I am getting this error.

Any help will be much appreciated.

Regards,
Ketan
