Robust statistical analyses can produce valid results even when the ideal conditions do not exist with real-world data. These analyses perform well when the sample data follow a variety of distributions and have unusual values. In other words, you can trust the results even when the assumptions are not fully satisfied. For … See more The mean, median, standard deviation, and interquartile range are sample statistics that estimate their corresponding populationvalues. Ideally, the sample values will be relatively close to the population value and … See more An intuitive way to understand the robustness of a statistic is to consider how many data points in a sample you can replace with artificial outliers before the sample statistic becomes a poor estimate. Statisticiansrefer to … See more There are several common measures of variability, including the standard deviation, range, and interquartile range. Which statistics are robust? The standard deviationis similar to … See more WebMay 12, 2014 · The papers review the state of the art in statistical robustness and cover topics ranging from robust estimation to the robustness of residual displays and robust smoothing.
