For each sample, we performed M estimates using three tentative θ values based on the long-term θ estimated by LAMARC (first row), θ = 0.5 (second row), and θ = 10 (third row), except for CADR and CSTY samples. In these samples, an estimate of M was also calculated using a short-term θ value (*) computed by the temporal method. Significant P values are presented in boldface.
