Sentence examples for unequal variation from inspiring English sources
The comparison shows that the proposed model is more precise and accurate than the OLS method in estimation of the regression coefficients by considering unequal variation between residuals.
This objective defines the inequality in time-series due to three sources: unequal tendency (mean), unequal variation (variance) and imperfect co-variation (co-variance) (Born 2001).
Statistical analysis was performed with student's t test assuming a two-tailed and unequal variation.
We used separate variances to account for unequal variation between categories of development [37].
PCs were computed separately for each species and patch using a covariance matrix in order to maintain unequal variation of the coordinates.
Two-tailed student's t tests for unequal variation were used to value significance levels.
Statistical significance of the difference between white and opaque a/a strains was determined using the t-test assuming unequal variations data analysis function in Microsoft Excel (Microsoft Corporation, Redmond, Washington, United States), setting a p-value of less than.001 for the one-tailed distribution as the significance threshold.
As the sensors showed unequal variations in resistance during inflation and deflation, and a degree of short-term inaction was apparent during the process of inflation, the first minute of data and the last 10 measurements were excluded from statistical analysis.
Two-tailed t tests (assuming unequal variance), and coefficients of variation % (CV%) were calculated in Microsoft Office Excel 2007.
Because some strains are more closely related than others, this could in theory introduce artifactual QTL, for example if one monophyletic clade had more variability for a trait than another (the potential pitfalls of measuring canalization in groups with unequal genetic variation have been stressed previously, e.g. [10]).
The average egg mass and variation (between parentheses) was calculated and compared with the saline-injected control ticks by Student's t-test with unequal variance.
