I see that "Bivariate Correlations" is in the list of supported procedures.  I assume that means that a correlation matrix is generated for each of the multiply imputed data sets, and that those estimates are pooled.  So couldn't one use that pooled correlation matrix as input for the exploratory factor analysis?

Hi Alex,

1. There are 2 different imputation methods: Fully conditional
specification (which uses MCMC) and Monotone.  See
http://publib.boulder.ibm.com/infocenter/spssstat/v20r0m0/topic/com.ibm.spss.statistics.help/idh_idd_mi_method.htm
for details.

2. I'm afraid Factor analysis does not currently support pooling of
multiple imputation data: See
http://publib.boulder.ibm.com/infocenter/spssstat/v20r0m0/topic/com.ibm.spss.statistics.help/mi_analysis.htm
for a list of procedures that do.  Procedures that do support pooling
automatically generate pooled output when run on multiply imputed
datasets.
