t*********e 发帖数: 313 | 1 Dear all,
I used PROC MI to impute missing values for some variables and created five
sets of data.
I am now struggling with how to get a valid final statistics (e.g., count,
percentage, mean, std., etc.) for those variables with five sets of imputed
values.
Any help would be highly appreciated.
Thanks | H******r 发帖数: 2879 | 2 proc mianalyze.
or you can search Rubin "multiple imputation combining rules", it is kind of
intuitive. | t*********e 发帖数: 313 | 3 Thank you for the tips. I also received some help from SAS technical
suppport. Proc mianalyze can be used to ge combined means and std err, not
std dev. At this point, neither SAS nor Stata can produced two-way tables
using all the imputed data sets. I was told I have to average across all the
imputed data sets to get sample size.
Thanks! | t*********e 发帖数: 313 | 4 By sample size, i mean the total count by subgroups in a two-way table.
Thanks! | t*********e 发帖数: 313 | 5 i actually ended with randomly selecting one data set for the univariate
table. Any better idea is very welceome |
