Alternative Testing Strategies

Abstract The probability of multilocus genotype counts conditional on allelic counts and on allelic independence provides a test statistic for independence within and between loci. As the number of loci increases and each sampled genotype becomes unique, the conditional probability becomes a function of total heterozygosity. In that case, it does not address between-locus dependence directly but only indirectly through detection of the Wahlund effect. Moreover, the test will reject the hypothesis of allelic independence only for small values of heterozygosity. Low heterozygosity is expected for population subdivision but not for population admixture. The test may therefore be inappropriate for admixed populations. If individuals with parents in two different populations are always considered to belong to one of the populations, then heterozygosity is increased in that population and the exact test should not be used for sparse data sets from that population. If such a case is suspected, then alternative testing strategies are suggested.

AbstractProgress in the debate over rational deterrence has always depended on the ability of scholars to identify a body of evidence that would be appropriate for testing a wide range of propositions derived from the theory. Notwithstanding the tremendous amount of time and energy spent on producing a suitable list of cases, and several noteworthy surveys of the literature, cumulative knowledge about deterrence, both as a theory and as a strategy, remains elusive. It still is unclear whether decision makers have acted according to the logic derived from standard applications of the theory. Moreover, the most prominent testing strategy, originally designed by Paul Huth and Bruce Russett, and later criticized and revised by Richard Ned Lebow and Janice Gross Stein, continues to be plagued by ongoing disputes over methods and case listings. Although debates over the accuracy of historical accounts are constructive, lingering divisions over coding of deterrence successes and failures have become counterproductive, primarily because each side has produced evidence to support their interpretation of events. Very little effort, by comparison, has been directed towards (a) developing alternative testing strategies that lie outside the success/failure framework, or (b) looking at a wider range of propositions derived from the theory. This analysis attempts the task, analyzing in the aggregate 28 cases of superpower rivalry.
