Index basing:

The starting point of the AUTO1 Group Price Index is January 2015 with a reference value of 100. From the index start, AUTO1 Group considers their European data consistent enough to provide representative insights into price developments.

Processed data:

The index includes all AUTO1 Group wholesale transactions since January 2015. The vehicles of the data set are representative of the European used car market.

Data Cleaning

Prices, ages and mileages outside the [0.5; 99.5] percentile range are considered as outliers and are not considered for the index.

Index Calculation

AUTO1 Group calculates the mean sales prices for each month. To provide a statistically robust analysis on the data set, those mean prices are calculated monthly based on various categories (for example vehicle classes, fuel types, mileage ranges) whose distributions are used as weights. The index is calculated based on current and aggregated past weights.

Seasonal Adjustment

A 12 months based additive decomposed model is used to extract and remove the seasonality component from the index.
