Odp: Dealing with NAs
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

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?
