The PCA applied to data corresponding to mycotoxins content registered in wheat samples harvested in 2011 using the correlation matrix led to a variance value of 58.51% for the first component (PC 1) and 29.02% for the second component (PC 2), so we chose to use the distribution only on the first two axes (with highest correlation variance), Figure 3b.
Because these are the most difficult and expensive parameters to measure, especially for thick deposits, other more convenient parameters are preferred, especially the couple (left( {V_{{{text{s}}30}},f_{0} } right)) that leads to a variance reduction in at least 60%.
For larger population sizes, σe in per capita population growth rates leads to a variance that tends to scale with the square of the mean and hence overshadows the variance from σd which scales directly with μ ¯.
In fact, adding age and sex to the model with the 22 SNPs led to a variance explained in KORA-F3 similar to that of popgen (24.3 versus 24.9%).
Multitapering using K tapers, however, can lead to a substantial variance reduction.
In such spawning aggregations, territorial behavior and reproductive competition among males may lead to a large variance in reproductive success among individual males.
Bites by spiders from Loxosceles genus often lead to a wide variance in envenomation profile of patients and diagnosis is difficult due to the number of diseases that mimic loxoscelism.
Thus, high values of these two parameters, even if they guarantee the OLLA convergence, may lead to a high variance in the instantaneous offset value that could degrade the OLLA performance.
For instance, elevated recombination would lead to a lower variance of Tajima's D and Rozas' R2, which would return growth estimates with less uncertainty, while elevated mutation rates would shorten our time frames, and hence return younger growth estimates.
Including the individuals with (a) missing item(s) did not lead to a decreased variance.
