However, the assumption of a health-related critical low aerobic power is also supported by several studies applying estimations of VO2max [ 17, 28– 31].
In a 2012 study, Kembel and coworkers [ 1] illustrated the importance of this problem by applying estimations of copy number to previously published metagenomic data sets, based on known copy numbers from diverse bacterial species.
28 30 Also the impact of the applied estimation strategy for biological factors is low as the estimates obtained with different approaches yield very similar results.
First of all, the applied estimation methods bear uncertainties which may result in false positive or false negative compounds.
We apply estimation of distribution algorithm to solve model (14) with assumption that the decision makers specify the optimism degree (gamma=0.6).
Most of the studies on the DS factor structure applied estimation methods that did not take into account the non-normality of item distributions [ 5].
In six out of twelve studies, the method of food record was applied: estimation using household measures was used in five studies [ 8- 15, 15, 33] and weighed food record was used in one study [ 7].
Results indicated that when operating within a familiar number range, a linear representation dominates from Year 2, but also there was indication that beginning in Year 2 children start to apply estimation strategies, which become more advanced in Year 3.
However, we must underline that potential sex-related differences in white blood cell proportions might not be captured by the applied estimation method and may thus confound our analysis to some extent.
