Web1 regression. All estimation methods rely on assumptions for their validity. We say that an estimator or statistical procedure is robust if it provides useful information even if some … WebOverview. R provides several methods for robust regression, to handle data with outliers. This tutorial shows how to fit a data set with a large outlier, comparing the results from both standard and robust regressions. This also serves as a comparison of plotting with base graphics vs. ggplot2, and demonstrates the power of using ggplot2 to ...
