Hi
I am trying to estimate parameter values with mlogit. I attach a part of my data.
My code is
x=mlogit.data(y,choice="voittaja",shape="long",id.var="id",alt.var="numero")
summary(mlogit(voittaja ~ Ie-1 , data=x, na.action=na.pass))
But i get
Error in if (abs(x - oldx) < ftol) { :
missing value where TRUE/FALSE needed
Because there is Na in D2.
What should i do to make it work?

Read the posting guide. An example is not reproducible without sample data.
You may need to remove data records containing NA. It may not even be a true NA, depending how you got your data into R.

Hi Without knowing details about mlogit and without any data from your side to check I guess that you shall put na.omit or na.exclude instead of na.pass to na.action Regards Petr
