where σ2y is the variance ofY(the correlation ratio η2XǀYis analogously defined, but there is no simple relation between ηYǀX and ηXǀY).The quantity η2YǀX, which varies from 0 to 1, is equal to zero if and only if the regression has the formy(x)= my, in which...
Correlations across therapy areas were tested by weighted Pearson’s correlation (wtd.cor from the R weights package, v.1.0.4); to control for the amount of data available in each therapy area, the number of genetically supported T–I pairs having reached at least phase I was used as the...
Two trained observers, blinded to the drug-stimulus pairings, analysed all videos for the duration of time the calf spent in contact with the conditioned stimulus (inter-observer reliability: intraclass correlation coefficient = 0.96). We defined contact as the muzzle or tongue touching the board ...
Note that serial correlation is not an issue in our balanced panel because the large number of periods with 0 publications breaks any time correlation for any given institution. *p < 0.1, **p < 0.05, ***p < 0.01. The marginal OARE effect ranges from +0.4% for institutions with a low ...

While we have focused on challenges from teachers’ choice in lessons, it is important to acknowledge other challenges. Consider, for example, the risk of Simpson's paradox (Blyth,1972). Simpson’s paradox occurs when an overall correlation disappears or reverses direction when looking within sub...
Differences between groups were assessed using Student’s t test, and correlations between groups were determined using the Pearson correlation coefficient. The CCK-8 assay data were analyzed using ANOVA. P < 0.05 was considered to be statistically significant. Results Identification of LINC0062...
In this algorithm τ and k are both tuning parameters, and they jointly determine the property of the estimated coefficients. When τ = 0, all coefficients are non-zero for all values of k, and TGDR provides a solution roughly corresponding to the ridge regression.1,9When τ = 1, the ...
Because of the high correlation between non-HDL cholesterol and apoB levels 3, 4, non-HDL cholesterol represents an acceptable surrogate marker for total apoB; the latter is not widely available for routine measurement in clinical practice. Therefore, ATP III (2)identifies the sum of LDL and ...
Correlation of circulating anti-EPO autoantibodies with anemia Univariate logistic regression analysis of identified baseline parameters of HCV-infected patients revealed that the presence of anti-EPO was associated with significantly increased risk for anemia (OR=4.345; 95% CI: 1.044-18.079;P=0.043). ...
