Missing Data Categorical variables

[eilayyan]

Hello,

I am going to run an ordinal regression model. I have missing values for both categorical and continous variables.

I know that i can use "proc mi" to handle the missing values, but what i should do with categorical variables?

Thanks

To clarify: Do you have missing values in categorical and continuous regressors?  Or are you saying that the ordinal response variable has missing values?

[eilayyan]

Yes, i have missing in the ordinal variables. also, i have missing in the predictor variables.

You should read Paul Allison's books and papers. Start with

Imputation of categorical variables with PROC MI
