In this study, we determined the conditions in which a target genotype can be fixed when truncation selection is applied on an epistatic trait.
Automatic backward logistic regression analyses were used at various levels of this nested procedure, according to four methods: automatic backward selection was applied to on 100 imputed datasets.
Model M2a (positive selection) was applied to each branch on the phylogeny and compared to model M1a (nearly neutral) to identify specific branches undergoing positive protein-coding adaptation.
In the model-fitting procedure, the strategy of stepwise variable selection was applied to include or exclude variables based on testing of whether their regression coefficients were significantly above zero.
Genome-wide study of allele frequency changes have also been performed in the Virginia chicken lines experiment in which selection was applied bi-directionally on body weight for 50 generations [ 43] with an effective population size around 35.
In a later version, a positive selection was applied that depends on the use of a specifically engineered cell [ 3] or a cell with an intact lacZ reporter gene.
Moreover, a new efficient feature selection method namely Orthogonal Forward Selection by incorporating Gram Schmidt procedure and forward selection is applied for selection of the best subset features.
Meanwhile, the Incremental Feature Selection and Forward Feature Selection are applied for feature selection.
