The message seems to suggest you go to your data editor and change the level of measurement from ordinal to scale.  If that doesn't work I'm sure some of the statisticians on the list will come up with an answer.

  I am trying to imputem missing values. I have a data set with 500 variables, both interval and ordinal. When I run the imputation, I get this error message:

  The imputation model for r022q1C contains more than 100 parameters. No missing values will be imputed. Reducing the number of effects in the imputation model, by merging sparse categories of categorical variables, changing the measurement level of ordinal variables to scale, removing two-way interactions, or specifying constraints on the roles of some variables, may resolve the problem. Alternatively increase the maximum number of parameters allowed on the MAXMODELPARAM keyword of the IMPUTE subcommand.
  Execution of this command stops.

  Any ideas on what I can do? The ro22q1C variable is an ordinal variable.

  Thanks!

  Courtney
