Web11 apr. 2024 · Abstract. The value at risk (VaR) and the conditional value at risk (CVaR) are two popular risk measures to hedge against the uncertainty of data. In this paper, we provide a computational toolbox for solving high-dimensional sparse linear regression problems under either VaR or CVaR measures, the former being nonconvex and the latter convex. WebLinear regression uses the least square method. The concept is to draw a line through all the plotted data points. The line is positioned in a way that it minimizes the distance to all of the data points. The distance is called "residuals" or "errors". The red dashed lines represents the distance from the data points to the drawn mathematical ...
