Abstract A new MATLAB based graphical user interface integrating several multivariate calibration transfer approaches is presented. Several methods for standard-based and standard-free are integrated. demonstration of the toolbox functionalities different was judged using a case corn dataset. All were tested on dataset results showed that ready to be used. The best feature it push-button even n...

A newly developed multivariate method involving net analyte preprocessing (NAP) was tested using central composite calibration designs of progressively decreasing size regarding the multivariate simultaneous spectrophotometric determination of three active components (phenylephrine, diphenhydramine and naphazoline) and one excipient (methylparaben) in nasal solutions. Its performance was evalua...

This paper describes a dynamic multivariate jump driven model in a credit setting. We set up a dynamic Lévy model, more precisely a Multivariate Variance Gamma (VG) model, for a series of correlated spreads. The parameters of the model come from a two step calibration procedure. First, a joint calibration on swaptions on the spreads is performed and second, a correlation matching procedure is a...

During the past decades, large amounts of diffuse cadmium (Cd) and zinc (Zn) contaminated soil material have been deposited in the floodplains of the river Rhine in the Netherlands. As spatial information on soil quality is required at different scale levels covering the whole area, characterisation exclusively based on soil sampling and analysis is time-consuming and very expensive. A quicker ...
