| Subject | st: st: Using MVN for Multiple Missing Ordinal Variables |
| Date | Sun, 08 May 2011 08:15:08 -0500 |
I have multiple missing values from a survey administered to a sample of just slightly over 150 persons. The items are structured in a ordered likert scale of between 5 and 8 items. I have checked missing patterns with misstable and most are not monotone. I need to impute missing values and generate descriptive statistics. I am wondering if Impute MI MVN method (mutivariate normal) with stata 11 would be appropriate for ordinal data? If it is, once I generate the 10 imputed datasets, should I simply average the imputed values and adjust the variance? Does anyone with experience working with missing values have any other suggestion for ordinal data?
