Coefficient of linkage disequilibrium
WebJan 1, 2024 · A particularly useful metric of linkage disequilibrium is r 2 which is equivalent to the Pearson correlation coefficient. r 2 is calculated as D 2 /(p 1 × p 2 × q 1 × q 2) and ranges from 0 to 1.Because it is less sensitive to extreme allele frequencies than D or D′, r 2 is commonly used to describe linkage disequilibrium in genetic epidemiologic … WebYou observe a value of 0.248 for the value of coefficient of linkage disequilibrium (D) …
