From the statistical point of view, if the target phenotype is considered as independent variable and allelic variation in many genome loci as explanatory variables, we need to pick up the variables with significant contribution to the phenotype from tens of thousands of variables. This is so-called variable selection from oversaturated models. There has been many methods to deal with this issue.

从统计学的角度来看，如果把目标性状表现型看作依变量，基因组上很多座位的序列变异看作自变量，则需要在成千上万个自变数中筛选出一些对表型有显著效应的自变数，因此，该问题可以看作是一个超饱和模型变数选择的问题。
