In multiple regression, different techniques are available to deal with the situation where predictors large in number, and multicollinearity exists among them. Some of these approaches rely on correlation others depend principal components. To cope influential observations (outliers, leverage, or both) data matrix for regression purposes, two proposed this paper. These Robust Correlation Based...

Online robust principal component analysis (RPCA) algorithms recursively decompose incoming data into low-rank and sparse components. However, they operate on vectors cannot directly be applied to higher-order arrays (e.g. video frames). In this paper, we propose a new online PCA algorithm that preserves the multi-dimensional structure of data. Our is based recently proposed tensor singular val...

This study analyses and compares various Principal Component-based methods of fixed income security immunization. We show that the methods are effective in terms of reducing the volatility of the security returns; however, none of the Principal Component-based techniques outperforms the mean-variance optimization. We conclude that the Principal Component-based immunization is more effective whe...
