Returns a 1-row matrix. The columns are:
F - F statistic for test of null hypothesis
dfA - degrees of freedom for between-subjects factor
dfE - error degrees of freedom
dfA - degrees of freedom for between-subjects factor
p - p-value for F-test
eta-squared - estimate of eta-squared
adj eta-squared - a bias adjusted estimate of eta-squared
