In order to verify the correctness of the MCAO procedure animals were tested for existence of a neurological deficit (ND) [ 16].
As shown in Table 1, all patients were HBV infected verified by both serological analysis and the PCR test for existence of the HBV X gene in tumor tissue (not shown).
The A594G and T652C variants, which distinguish the two haplotype groups, condition NsiI and SphI restriction sites, respectively, and we used this to test for existence of distinctive haplotypes in the FF+5A.
Models that take into account the existence of a major QTL (major sex-determining region) or ones that test for existence of multiple QTLs simultaneously reduce the residual variation - providing higher power in the analysis for detecting additional QTLs at least of moderate effect [ 27].
Even though models that take into account the existence of a major QTL (as in this study) or ones that test for existence of multiple QTLs simultaneously reduce the residual variation (providing this way higher power in the analysis for detecting additional QTLs at least of modest effect), no additional QTLs were detected.
The Mann–Whitney U-test, which tests for the existence of systematic differences between the efficiency scores, is adopted.
The study not only tests for the existence of price transmission between international rice markets but also the direction of price transmission.
It is, of course, open to them to adopt a unified view and treat every explicit or implicit legal reference to morality -- in cases, statutes, constitutions, and customs -- as establishing moral tests for the existence of law.
The first was an extension of the DD model known as a difference-in-difference-in-differences model (DDD) which tests for the existence of factors that differentially affect screening rates in Ontario in the post-intervention period which could mistakenly be attributed as impacts of the ColonCancerCheck program.
The coefficient β3 is also informative, in that it provides the basis to test for the existence of pre-policy differences in trends between high and low competition places β3 ≠ 0. The existence of pre-policy differences in trends would undermine the credibility of the DiD strategy.
