Current evidence, based on the variance of sex-ratio between families, suggests the existence of a polygenic sex determination system [ 17].
It is based on the variance in time spent near the predator between individuals relative to that within individuals.
The ICCAGREEMENT was calculated as the ratio of the between-subject variance and the total variance, based on the variance components obtained with the repeated measures analysis of variance (ANOVA) technique in IBM SPSS Statistics 20.
Based on the variance analysis for all four examples, we found no significant difference between the solutions.
These distributions were based on the variance-covariance matrices of the parameters describing the relationship between metamorphosis success and Cu concentration at each temperature.
Based on maximizing the variance between the groups and minimizing it within the six groups in the classification matrix we could classify the 257 coins into three groups.
The optimal k-value, i.e. 4 for the initially up-regulated and 6 for initially down-regulated genes, were based on the explained variance between clusters and the overrepresentation of functional categories (for detailed explanation please refer to Additional file 3).
The pooled variance or the Satterthwaite's method was used to estimate variance based on the equality of variance test.
Because heritability estimates are based on the contrast of between and within family variance and QTL variance is based mainly on within family variance low trait heritability is not expected to affect QTL detection.
In practice, it is often possible to estimate one variance value based on data, and then specify the other variances based on the expected variance trend.
The threshold method was developed based on the derivative of the between-class variance (Otsu, 1979; Lin, 2003).
