We proposed a robust method of estimating covariance matrix in multivariate data set. The goal is to compare the proposed method with the most widely used robust methods (Minimum Volume El-lipsoid and Minimum Covariance Determinant) and the classical method (MLE) in detection of outliers at...

The ideal measure of inflation should reflect long-run price movements driven by actual demand in the economy and exclude short-term supply shocks. Considering that the CPI does not correspond to such a measure, the purpose of this research is to analyze alternative methods of core (or...
