Furthermore, our simulations suggest that, even without correction for multiple testing, this approach will lack power compared to sex-differentiated tests of association when causal variants have allelic effects in both males and females, but which differ in direction and/or magnitude between them.
Within this framework, we propose a sex-differentiated test of association, and demonstrate how we can test for heterogeneity of allelic effects between males and females.
We can perform a sex-differentiated test of association across all studies at the jth SNP, allowing for different allelic effects in males and females, given by, and having a chi-squared distribution with two degrees of freedom.
In this article, we review the methodology for meta-analysis of sex-specific genome-wide association studies, and propose a sex-differentiated test of association with quantitative or dichotomous traits, which allows for heterogeneity of allelic effects between males and females.
We present results obtained on a wide area differentiated services testbed that demonstrate our ability to deliver QoS for realistic flows.
Given the current data these two alternative hypotheses cannot be differentiated or tested.
The heterogenous species Y. enterocolitica encompass six biotypes as differentiated upon biochemical tests [ 9].
The molecular genetic investigations identified our isolate as C. pseudogenitalium and placed it in 1 of the 2 genomic groups of CDC group F-1, which cannot be differentiated by biochemical tests (1 ).
The three most clinically relevant Acinetobacter species, Acinetobacter baumannii, Acinetobacter nosocomialis (formerly Acinetobacter genomic species 13TU), and Acinetobacter pittii (formerly Acinetobacter genomic species 3), cannot be differentiated by phenotypic tests used in clinical microbiological laboratories and are grouped as the A. baumannii (Ab) group [ 1].
The classical and El Tor biotypes are differentiated by phenotypic tests (1 ), and several nucleotide base differences occur at positions 115 and 203 in the ctxB gene (C in both positions in the classical and T in both positions in the El Tor biotype).
The results were expressed as "percent activity" with respect to ATP ("max" signal for the undifferentiated cells; final test concentration: 100 µM) and glutamate ("max" signal for the differentiated cells; final test concentration: 100 µM).
