Permutation test for linear regression
WebWe tested the significance of β > 0 $$ \beta >0 $$ using a permutation test, where ages were randomly permuted among individuals for 10,000 times to generate the empirical null distribution. This analysis was also conducted for female–female pairs and male–male pairs separately. ... Significant, positive coefficients in the linear ... WebDescription.
