Jede Zeile bezeichnet ein PKW-Modell. Die Variable make enthält die Bezeichnung des Modells und die Variable price den Preis in $. Die restlichen Variablen enthalten verschiedene technische Kennzahlen wie mpg (miles per gallon) oder headroom (Hubraum)..

If 0 p exceeds 1 P, the loss will be positive.If 0 p is less than 1 P, the loss will be negative, which is another way of saying the portfolio makes a profit.. Calculating Value-at-Risk as a Quantile of Loss.
