Hello R Users,
I am trying to use the svyolr command and coming up with the following error:
Error in MASS::polr(formula, data = df, ..., Hess = TRUE, model = FALSE, :
attempt to find suitable starting values failed
>From what I have read online, a possible solution is to specify a value in the
>start argument of svyolr; unfortunately, I have not been able to find any
>detailed/clear descriptions about how to go about specifying values for the
>start argument. Any help in explaining how to go about establishing
>reasonable start values would be greatly appreciated.
