WebMar 26, 2024 · You find an r2 of 0.45 with a p value less than 0.05 for model 1, and an r 2 of 0.46 with a p value less than 0.05 for model 2. Model 2 fits the data slightly better – but was it worth it to add another parameter just to get this small increase in model fit? WebThe extended Langmuir model (EL) showed competitive HM immobilization since there was a decrease in the IMAX of Zn (∼90 ± 28 mg kg–1 from SGB) and Cd (∼0.70 ± 0.21 mg kg–1). Negative values of Pb and Cd immobilization at low rates of SGB indicated an increase in those HM availabilities and preferential immobilization for Zn. mohre ministry of human
