Exactly When is Rare Variant Analysis … This is the Combined and Multivariate Collapsing (CMC, Li and Leal, 2008) test for rare variants. CMC method considers all variants in a test unit (e.g., a gene). It “collapses” all rare variants in the gene region such that the region is coded “0” if all loci are wildtype, and “1” if any one locus has a minor allele.

WebIn this study, it is shown that the collapsing method, which involves collapsing genotypes across variants and applying a univariate test, is powerful for analyzing rare variants, whereas multivariate analysis is robust against inclusion of noncausal variants. Both methods are superior to analyzing each variant individually with univariate tests. WebIf variables x1 and x2 represent two different methods to measure the same element, combining the two can provide a more accurate description of the element you wish to measure. E.g. if you need a variable that indicates body size, one can combine variables x1 = height and x2 = weight, either by summing x1 + x2 or by peforming a principal ...
