We will start with a huge dataset from an insurance company, we are going to optimize this dataset and reduce the number of model point without losing significant accuracy. We do this with the Nonnegative Least Squares (NNLS) method. In this thesis, NNLS will be described briefly, results and conclusions from the NNLS optimization are shown and discussed.enmittenegatiivne vähimruutude meetodmudelpunktidelukindlustusmagistritöödnon-negative least squaresmodel pointslife insuranceThesis
