You can obtain Bartlett's test of sphericity in SAS/STAT® software by specifying the options METHOD=ML and HEYWOOD on the PROC FACTOR statement. For example:

proc factor method=ml heywood;

An excerpt from a sample output appears below.


          Initial Factor Method: Maximum Likelihood

          Significance Tests Based on 19 Observations

H0: No common factors                  3       41.3313    <.0001
HA: At least one common factor
H0: 1 Factor is sufficient             0        0.0000    <.0001
HA: More factors are needed

The row H0: No common factors contains the degrees of freedom, chi-square statistic, and p-value corresponding to Bartlett's test of sphericity.
