EPWerten
EPWerten is a statistical concept used to summarize an observation within a data set by combining its percentile rank with a value-based normalization into a single metric. The aim is to provide a compact, comparable measure that reflects both the position of a data point in the distribution and its absolute magnitude on a standardized scale.
In practice, EPWerten relies on two components for each observation: a percentile rank P, typically expressed
Common applications of EPWerten include performance evaluation, risk assessment, and quality control, where stakeholders need a
Advantages of the approach include robustness to extreme values (through percentile components) and interpretability (a score
