چکیده
Abstract. Outliers are datums that far from other datums. arise as a result of unusual events may be very important and need to investigated further. usually found in data has daily characteristics such stock data. With this outlier, the T2 Hotelling control chart used average vector shift becomes insensitive changes process. This thesis discusses for Minimum Volume Ellipssoid (MVE) estimator which is not affected by outliers. then applied index PT X Joint Stock (JCI) simultaneously. The results tests carried out show MVE more effective detecting outliers, namely there 13 with UCL value 5.5025.
 Abstrak. Pencilan merupakan datum yang letaknya jauh dari lainnya. muncul akibat kejadian tidak biasa mungkin saja sangat penting dan perlu diselidiki lebih jauh. biasanya terdapat pada memiliki karakteristik harian seperti saham. Dengan adanya pencilan tersebut diagram kontrol digunakan untuk mengontrol pergeseran vektor rata-rata menjadi peka terhadap perubahan proses. Skripsi ini membahas penduga Elipssoid terpengaruh pencilan. Diagran kemudian diaplikasikan pengontrolan indeks saham Saham Gabungan (IHSG) secara simultan. Hasil pengujian dilakukan menunjukkan bahwa efektif dalam mendeteksi yaitu sebanyak dengan nilai BKA sebesar 5,5025.

The Minimum Volume Ellipsoid Metric
We propose an unsupervised “local learning” algorithm for learning a metric in the input space. Geometrically, for a given query point, the algorithm finds the minimum volume ellipsoid (MVE) covering its neighborhood which characterizes the correlations and variances of its neighborhood variables. Algebraically, the algorithm maximizes the determinant of the local covariance matrix which amount...

متن کاملOn the Minimum Volume Covering Ellipsoid of Ellipsoids
We study the problem of computing a (1+ )-approximation to the minimum volume covering ellipsoid of a given set S of the convex hull of m full-dimensional ellipsoids in Rn. We extend the first-order algorithm of Kumar and Yıldırım that computes an approximation to the minimum volume covering ellipsoid of a finite set of points in Rn, which, in turn, is a modification of Khachiyan’s algorithm. F...
متن کاملOn the Minimum Volume Covering Ellipsoid of Ellipsoids
Let S denote the convex hull of m full-dimensional ellipsoids in Rn. Given > 0 and δ > 0, we study the problems of computing a (1 + )-approximation to the minimum volume covering ellipsoid of S and a (1 + δ)n-rounding of S. We extend the first-order algorithm of Kumar and Yıldırım that computes an approximation to the minimum volume covering ellipsoid of a finite set of points in Rn, which, in ...
متن کاملLocation adjustment for the minimum volume ellipsoid estimator
Estimating multivariate location and scatter with both affine equivariance and positive breakdown has always been difficult. A well-known estimator which satisfies both properties is the Minimum Volume Ellipsoid Estimator (MVE). Computing the exact MVE is often not feasible, so one usually resorts to an approximate algorithm. In the regression setup, algorithms for positive-breakdown estimators...
