Interactive Outlier Detection

The goal of the workflow is to identify outliers in the medical claim data such as claims with an unusual high cost for a certain disease In order to find these outliers the input data is group by the target variable (disease) and the mean and standard deviation is computed for the numerical variable in question (cost of stay). Outliers are all records that deviate more than x*standard deviation from the mean value of the group they belong to whereas the factor x e.g. 2 is specified by the analyst.
