Estimação e testes de hipóteses em calibração comparativa / Estimationin hypotheses testings of comparative calibration




We know about the literature that Comparative Calibration it is linked the efficiency comparison of measurement instruments. In this work we discuss estimates and tests of hypotheses in comparative calibration models. For the estimate of the parameters of the model, we consider the EM algorithm and the algorithm BFGS in the program Ox. Testings for some hypotheses of interest are implemented using the likelihood ratio and Wald statistics. Simulation studies are used in the comparison of the procedures. An application is presented to a data set, constituted of measurements of heights of trees with three, four and five hipsometers.
