Hello everyone, I am using *mlogit* to analyse my choice experiment data. I have *3 alternatives* for each individual and for each individual I have *9 questions*. I have a response from *516 individuals*. So it is a panel of 9*516 observations. I have arranged the data in long format (it contains 100 columns indicating different variables and identifiers).
In mlogit I tried the following command--- *mldata<- mlogit.data(mydata, shape = "long", alt.var = "Alt_name", choice = "Choice_binary", id.var = "IND")* It is giving me the following error message- Error in 1:nchid : result would be too long a vector Could you please help me with this? I don't think it is too big a data 100 ROWS*13932 columns. I faced no issue in Excel. I am stuck due to this issue. Thanks in advance. -- Best Regards, Rahul Chakraborty Research Fellow National Institute of Public Finance and Policy New Delhi- 110067 [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
