WebMay 13, 2024 · The paper has the following structure. A stipulation about the expected value of Tukey’s biweight loss function is introduced in Sect. 2. Then Sect. 3 will apply this loss function to compute the unknown parameters in the uncertain regression models, and the choice of the parameter in the Tukey biweight function is discussed by cross-validation. Webbisquare (or biweight) estimator. The objective and weight functions for the three estimators are also given in Table 1. Both the least-squares and Huber objective functions increase without bound as the residual edeparts from 0, but the least-squares objective function increases more rapidly. In contrast,

WebTools. In statistics, biweight midcorrelation (also called bicor) is a measure of similarity between samples. It is median -based, rather than mean -based, thus is less sensitive to outliers, and can be a robust alternative to other similarity metrics, such as Pearson correlation or mutual information.

The figure shows the calculation of the biweight estimator in Excel using 20 iterations (iterations 4 through 17 are not displayed), resulting in a value of 48.11807 (cell AU3). Actually, this level of precision was reached after only 13 iterations.

WebUsing a biweight scale and a tuning constant of c = 6, the biweight attains an efficiency of 98.2% for samples of size 20 from the Gaussian distribution. The minimum efficiency at n = 20 using the biweight scale and c = 4 is 84..%, revealing that the biweight performs well even when the underlying distibution of the samples has abnormauly ...
