To test returns for autocorrelation, Lo (2001) suggests the use of the
Ljung-Box test, a significance test for the auto-correlation coefficients.
Ljung and Box (1978) provide a refinement of the Q-statistic proposed by Box
and Pierce (1970) that offers a better fit for the chi^2 test
for small sample sizes. Box.test
provides both.
