Hi all,

I found in several articles that it makes sense to split a sample in
two to derive the (yet unknown) factor structure from the first half
using EFA and then to test this structure using CFA with the second
half. I would consider it bad practice to use both strategies on the
entire sample; however, a colleague of mine disagrees. I have been
searching for arguments/references in favor of my assumption but was
not too successful (except for a lecture script, which does not
mention any references, I did not find anything specific). Any hints
would be appreciated.

Regards
Tanja
