WebbThe test for multiple clustering was based on the chi-square approxi-mation. In all cases we have assumed that the alternative to randomness is some form of clustering. Therefore the hypothesis of randomness is rejected for large values of s2 for the test for multiple clustering, large negative values of Z for the runs test and the test for WebbDescription. h = runstest (x) returns a test decision for the null hypothesis that the values in the data vector x come in random order, against the alternative that they do not. The test is based on the number of runs of consecutive values above or below the mean of x. The result h is 1 if the test rejects the null hypothesis at the 5% ...
