Robust estimation for dependent observations
Webdependent data. There is a vast literature on robust methods in econometrics and statistics. A line of research that is highly relevant to the current paper is initiated by a seminal paper by Beran (1977). It considers robust estimation of parametric models with IID data, and shows that the minimum WebFor the robust estimation of p linear regression coefficients, the elemental- set algorithm selects at random and without replacement p observations from the sample of n data. This elemental set is just sufficient to “estimate” the p regression coefficients, which in turn generate n residuals.
