    摘要: The present invention relates to a method (200) for generating a multivariate system model of a multivariate system which has a plurality of parameters and the multivariate system model is representative for the system response to changes in the parameters. The method (200) involves performing a plurality of measurements and/or simulations on the multivariate system to obtain reference data (201). The method further involves the selection of rational base functions (202) and combining these base functions (203) into a model of the multivariate system. The multivariate system model is obtained (208) by minimizing a cost function (205) between the model and the reference data. Explicit weight factors which are related to the reference data are used. The respective values for the explicit weight factors in the cost function are iteratively determined (205) in order to approximate the reference data with the model and the cost function is updated accordingly in each iteration.
