2016 International Journal of Osteoarchaeology  
Although the ancestry is a parameter of the biological profile mainly estimated in forensic Anthropology, this study confirms the importance of its investigation in past populations.  ...  The aim of the present study is to estimate the ancestry of a sample of 33 adult individuals (28 females and 5 males) recovered in the Valle da Gafaria applying the eleven morphological characteristics  ...  It is important to note that unless the data is projected into a subspace with forced orthogonality (i.e., PCA scores), it is common to observe some degree of dependency among predictors, which normally  ...

2022 Genes  
This, however, can be predicted by analysing epigenetic data.  ...  A significant challenge in developing universal genomic predictive methods will be the collection of sufficiently large data sets.  ...  Another important class of models are random subspace methods (RSM), in which each base classifier is learnt using the randomly selected subset of variables [147, 148] .  ...

2020 Genome Biology and Evolution  
Population genetic structure Sampled individuals were projected into a subspace spanned by the first principal components (PCs) using their genotypes as features.  ...  To minimize the effect of linkage and non-neutrality, the STRUCTURE analysis was based on a subset of all SNPs (a total of 199,921) where each contig contributes one random SNP from a non-coding region  ...
