st: table & chi-square from multiply imputed survey data (-ice-, -mim-) [repost] |

(Sorry for the repost, but I initially sent this as part of an unrelated
thread.)
I want to know how to generate a survey-adjusted chi-square like that
available from -svy: tab- using data multiply imputed using -ice- (net
sj 8-1 st0139).
I'd also be interested in suggestions about how to tabulate these data.
(E.g., would anybody complain if I computed a mean imputed value for
each variable for each case, rounded them off, and reported that?)
Suppose I have two variables, A & B, each with five categories, each
measured in survey from a complex design, each with about 10% missing
data. I want to see a 5x5 table with a chi-square statistic allowing an
inference about the independence (or not) of A & B. I can impute A & B
(and some other variables at the same time) using -ice-, but then what
do I do?
As far as I can tell, -mim- doesn't support -tab- or -svy: tab-, and
-svy: tab- itself doesn't support prefix commands. I can try predicting
A from B using -mlogit-, but that seems silly. I can manually do a
tabulation for each imputation and, I guess, average the chi-square
statistics, and, I dunno, subtract one degree of freedom, perhaps? I
don't see anything relevant in the list logs. Suggestions or pointers to
relevant lit?
Thanks.
Michael
