| <div class="block">Scale features using statistics that are robust to outliers. |
| RobustScaler removes the median and scales the data according to the quantile range. |
| The quantile range is by default IQR (Interquartile Range, quantile range between the |
| 1st quartile = 25th quantile and the 3rd quartile = 75th quantile) but can be configured. |
| Centering and scaling happen independently on each feature by computing the relevant |
| statistics on the samples in the training set. Median and quantile range are then |
| stored to be used on later data using the transform method. |
| Standardization of a dataset is a common requirement for many machine learning estimators. |
| Typically this is done by removing the mean and scaling to unit variance. However, |
| outliers can often influence the sample mean / variance in a negative way. |
| In such cases, the median and the quantile range often give better results. |
| Note that NaN values are ignored in the computation of medians and ranges.</div> |
