Dear Team, I am running a multinomial logistic regression model for one of the fictitious data before i implement the same on my real data. Here i am trying to predict based some scores and economic group whether a person will go for a diploma, general or honors. The code below: m11$prog2<- relevel(m11$prog, ref = "honors" already loaded the nnet library. However i got the below error: Error in relevel.factor(m11$prog, ref = "honors") : 'ref' must be an existing level I have tried searching on SO and nabble but did not find an answer that could help. Please suggest what is incorrect. Also checked the class of the var and is a factor variable. [[alternative HTML version deleted]]
