Mauchly test is a test which a variance-covariance matrix of pair wise differences of responses in the set of longitudinal data is the scalar multiple of identity matrix, a property known as sphericity.

Of most importance in the analysis of the longitudinal data where this property should hold for the F-tests in the analysis of variance of such type of data to be valid.
