- TL;DR Summary
- What exactly is tested with Bartlett's sphericity test? Is it equality of variances in dependent samples or is it an identity matrix?
In SPSS with the command sequence:
Analysis / Dimension reduction / Factor / PRINT KMO
Bartlett's sphericity test can be calculated. Now I read on:
https://www.itl.nist.gov/div898/handbook/eda/section3/eda35a.htm
that this test is a test for equal variances in dependent samples. My question is whether that is indeed the case. Because on Youtube:
it is claimed that the test would also test for zero correlations in the correlation matrix. What exactly is the case now? Is both the case and how is that possible?
