WebNov 8, 2024 · Robustness to non-constant variance (or heteroscedasticity) In the case of tests, robustness usually refers to the test still being valid given such a change. In other … Robust statistics are statistics with good performance for data drawn from a wide range of probability distributions, especially for distributions that are not normal. Robust statistical methods have been developed for many common problems, such as estimating location, scale, and regression parameters. One … See more Robust statistics seek to provide methods that emulate popular statistical methods, but are not unduly affected by outliers or other small departures from model assumptions. In statistics, classical estimation methods … See more There are various definitions of a "robust statistic." Strictly speaking, a robust statistic is resistant to errors in the results, produced by deviations from assumptions (e.g., of normality). … See more The basic tools used to describe and measure robustness are the breakdown point, the influence function and the sensitivity curve. Breakdown point See more A pivotal quantity is a function of data, whose underlying population distribution is a member of a parametric family, that is not dependent on the values of the parameters.
