H = TRIPLESTEST(X) performs the non-parametric triples test for symmetry (skewness) of the null hypothesis that the data in X comes from a symmetrical distribution with an unknown median. The test involves the examination of subsets of three variables from X (triples) to determine the likelihood that the distribution is skewed. H==0 indicated that the null hypothesis cannot be rejected at the 5% significance level. H==1 indicates that the null hypothesis can be rejected at the 5% level.

This test is suitable for date measured on a ordinal, interval, and rational scales, wheres the 3rd central moment (skewness) is valid for a rational scale only.

The syntax follows the style of most statistical tests in matlab. Note that the statistical toolbox is not required.
