Note, however, that at the Lapace distribution, the median has a 100% e ciency. The class of M-estimators yields estimators that are highly e cient and robust at the same time, and we will discuss them in a next section.

SpletWhy is median robust to outliers? In the presence of outliers, or extreme values, the median is preferred over the mean. The reason for this is that the mean can be “dragged” up or down by extreme values, but since the median is just the middle value in a distribution, it is not influenced by the outliers. ...

The mean is not a robust measure of central tendency. If the dataset is e.g. the values {2,3,5,6,9}, then if we add another datapoint with value -1000 or +1000 to the data, the resulting mean will be very different to the mean of the original data. Similarly, if we replace one of the values with a datapoint of … Prikaži več Robust statistics are statistics with good performance for data drawn from a wide range of probability distributions, especially for distributions that are not normal.
