It will be much more difficult to guaranty that other factors are evenly and randomly distributed across the samples, introducing the possibility that metabolic differentiation derives from unknown biases present in the sample set.
Estimated dates of introduction of Wasmannia auropunctata in the sampled introduced range.
As third analysis, we performed an exclusion analysis using GeneClass2 (Piry et al. 2004) to further investigate which native populations were genetically the most likely sources of the individual genotypes of the sampled introduced populations collected for the thermotolerance experiments.
Incomplete engagement of accessed members of the sample introduces further opportunities for selection bias, which should be recognized and controlled.
Incomplete access to all identified members of the sample introduces multiple opportunities for selection bias, which should be recognized and controlled.
We have previously shown that such between-individual variation in trappability is associated with the differences in the screened behaviors, and the elimination of non-captured birds from the sample introduces bias when assessing behavioral correlations (Garamszegi et al. 2009).
Regarding the new samples introduced in this study, the Anatolian Greek component was approved by the IRB of Aristotle University, Thessaloniki, Greece.
Nonetheless, the process of generating simulative samples introduced the noisy data, which decrease the classification accuracy especially for positive samples.
The CSF-based QC samples introduced into the method are stable under conditions expected during normal assay execution, and CSF samples can be stored at −70°C for at least 3 months.
Significant differences between the characteristics of the prison and general population samples introduced a large selection bias that could have compromised the inferences based on our estimations.
