Hello everyone,


?


Does anybody know whether it's possible to calculate extract major axis regression residuals on the results of a major axis Model II regression done by lmodel2?


Many thanks,


Orca

Model II regression

Call: lmodel2(formula = SSTo ~ SSTp, data = data1, range.y =


"interval", range.x = "interval", nperm = 99)


?


n = 26?? r = 0.5671202?? r-square = 0.3216254


Parametric P-values:?? 2-tailed = 0.002517785??? 1-tailed = 0.001258892


Angle between the two OLS regression lines = 30.86925 degrees


?


Permutation tests of OLS, MA, RMA slopes: 1-tailed, tail corresponding to sign


A permutation test of r is equivalent to a permutation test of the OLS slope


P-perm for SMA = NA because the SMA slope cannot be tested
