Thanks, Katharina Here the output of my lmodel2 regression: Model II regression Call: lmodel2(formula = log(AGB) ~ log(BM_roots), data = biomass_data, range.y = "interval", range.x = "interval", nperm = 99) n = 1969 r = 0.9752432 r-square = 0.9510993 Parametric P-values: 2-tailed = 0 1-tailed = 0 Angle between the two OLS regression lines = 1.433308 degrees Permutation tests of OLS, MA, RMA s...
