The analysis of several plausible nested alternative stock return generating processes suggests that stock returns with weak asymptotic tail dependence will produce CoVaR and MES hypothesis test statistic distributions that significantly overlap the sampling distributions of test statistics calculated from Gaussian returns.
Of course, since finding the probability of rejecting a true hypothesis requires testing that hypothesis, this necessarily tells DNA analysts to test an appropriate hypothesis and report the results of the hypothesis test and its level of statistical significance, which is of course the probability of finding a false positive.

Thus, in data mining procedures that use a sequence of hypothesis tests, the alpha level of the tests cannot generally be taken as an estimate of any error probability related to the outcome of the search.
