WebThe huber function calculates the Huber loss using dlarray data. Using dlarray objects makes working with high dimensional data easier by allowing you to label the … Web10.9.1 MM-Estimator. Yet another robust regression estimator that should be mentioned is the MM-estimator derived by Yohai (1987), which has certain similarities to the generalized M-estimators in Section 10.8. It has the highest possible breakdown point, 0.5, and high efficiency under normality. The parameters are estimated by solving an ...

Webi is an unknown value we would like to estimate with Fθ(xi), yi is a known estimate of y∗ i, and ǫ1 and ǫ2 are random noise variables drawn independently from sep-arate but known distributions. Since y∗ i is hidden, we are unable to estimate θˆby directly maximizing the likelihood of y∗ i given xi. Alternatively, we can estimate ...
