## Abstract The authors study the local influence of observations in multilevel regression models. To this end, they perturb simultaneously the variances, responses and design matrix. To measure the local change caused by these perturbations, they use generalized Cook statistics for the fixed and r
Multivariate calibration models are constructed using measured responses of variables (e.g. spectra) on a set of calibration samples and values of a quantity of interest (e.g. concentration) measured by a reference method. The goal is to replace the reference method. Traditionally the calibration da
