By contrast, CV for the various effect classes indicated that multiplicative adjustment factors tended to equalize variances among classes and, therefore, more nearly equalized impacts on EBV of weaning weight records from different types of lambs, but would overcompensate for the larger SD observed in single lambs.
We Log10 transformed these phenotypic characters to enhance normality and equalize variances.
Box-Cox transformation of IT values was performed to improve the normality of the distributions and equalize variances to meet assumptions [ 57], thus making the transformed data symmetric.
Log values were used to equalize variances among environments and BLUP means were used to help reduce the effect of extreme values (see Figure 2).
Analyses were performed on log-transformed laboratory values to normalize the distributions and to equalize variances, and transformed means were exponentiated to obtain geometric means.
To evaluate the relationship of CD146 to other markers in different patient groups, two-way anova was performed using log-transformed data, if necessary, to equalize variances; geometric mean frequencies were reported with 95% confidence intervals.
For those herbicides consistently detected in July, we tested if concentrations were significantly greater in July samples than in early spring samples (April/May) with a one-way, paired two-sample t-test (p < 0.05, data were log-transformed to equalize variances).
Additive factors were somewhat less effective in equalizing variances among fixed effect classes, but more effective in accounting for across-flock bias.
After some experiments, we decided to equalize the variance in the gammatone bands.
A straight-forward empirical and experimental test of this simulation result if, in fact, network size underlying a particular trait varies between species is to find two species with different-size networks, equalize additive variance for the trait, and then measure the response to selection.
