Wai et al. (2008) shows heteroplasmy variance rising during folliculogenesis, after the mtDNA copy number minimum has been passed.
Plus while incomes are rising, there's extraordinary variance in what price point the population can afford for a music subscription.
The same argument can be made for Figure 2; further, for Figure 2A, variance appears more or less constant, whereas for Figure 2B, variance rises between 1993 and 2000; F = 10 > 1.94 = F (df = 250, df = 250; percentile, 0.999).
Interesting is also Hg R2-M124 for which the Tharu total variance rises to 0.271, a value obtained by adding just two samples from the other Tharu groups to six homogeneous Th-CII samples (variance 0.033), thus stressing again the Tharu heterogeneity.
Increasing values of material imperfection variances and the rising excitation frequency can lead to a critical state when the length of the propagating wave is comparable with the correlation length of imperfections.
When the region containing this pattern is compared to another population with no history of selection, a rise in variance of allele frequencies between populations is observed.
As clinical test situations typically have several sources of error giving rise to variance in scores, a more thorough examination of the generalizability of the assessment instrument is needed.
Since most real life test situations typically do have more than one source of error giving rise to variance in scores, reliability coefficients rooted in GT ('generalizability' coefficients) are more often than not less biased estimates of reliability, than the more commonly used CTT coefficients (e.g. Cronbachs' alpha, Intraclass correlation coefficients and kappa coefficients etc).
Therefore, the change of the dynamical mechanism that happens with rising Bcd amplitude effectively doubles the variance.
The effects of reduced variance of output together with rising "inputs" may be inter-twined such as to also reduce the IQ/job-performance correlation over time.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
