“…31 They are not clearly defined, however, for multivariate calibration methods, although the literature indicates various strategies. 32,34,35 In this work, similar to Blanco, 36 validation was performed to evaluate these parameters: sensibility, selectivity, limit of detection, robustness, accuracy and precision. In the robustness test the same variables were evaluated as in the derivative methods.…”

“…31,32 The proposed NIR method was validated in accordance with ANVISA 25 and ICH 26,27 guidelines. Selectivity, linearity, repeatability, intermediate precision, accuracy, robustness and range were estimated as required by ANVISA.…”

“…The sensitivity (SEN) of a multivariate method can be estimated as the NAS at unit concentration, 31,32 according to equation 3. A more informative FOM is the analytical sensitivity (g), which is defined, in analogy with univariate calibration, 36 as the ratio between SEN and the instrumental noise, as expressed in equation 4.…”
