Dear List,
In my dataset of 28 variables I have two that are multinomial distributed (religious
denomination and main work activity). When I set them to nominal in the variables option
in the very newest version of Amelia, I get the following error code:
There was an unexpected error in the execution of Amelia.
Double check all inputs for errors and take note of the error message:
Error in chol(theta[c(FALSE, m[ss, ]), c(FALSE, m[ss, ])]) :
the leading minor of order 1 is not positive definite
Setting the two nominal variables to "no transformation", Amelia runs. Surely
there is a better solution?
Thank you very much for your help!
All the best,
Katharina
