I've got data in the form of
rec policyno reason2 uwclass sexx term band
1 1 17B356313 IS S M 30 2
2 2 17B356326 IS P M 20 3
when I use > mydata<-mlogit.data(poldata, choice="reason2",
shape = "wide",
reflevel="IS")
the result is
rec policyno reason2 uwclass sexx term band chid alt
1. 1 17B356313 FALSE S M 30 2 1
1.DE 1 17B356313 FALSE S M 30 2 1 DE
1.IS 1 17B356313 TRUE S M 30 2 1 IS
1.NT 1 17B356313 FALSE S M 30 2 1 NT
2. 2 17B356326 FALSE P M 20 3 2
2.DE 2 17B356326 FALSE P M 20 3 2 DE
2.IS 2 17B356326 TRUE P M 20 3 2 IS
2.NT 2 17B356326 FALSE P M 20 3 2 NT
I've tried using mydata<-mlogit.data(poldata, choice="reason2",
shape "tall", alt.levels = c("IS", "DE",
"NT"))
but just get an error message.
Any ideas?
