Abstract
Transactions involving assets that share a common characteristic are represented as respective data points associated with values of the assets. The data points include transaction value information. Respective statistical values are determined for the data points with respect to a probability density function that fits a power law parameterization to the data points. A probability function describing the statistical values is evaluated as a measure of confidence that the probability density function of the data points is validly represented by the power law parametrization.

A computer-based method comprising
- representing transactions involving assets that share a common characteristic, as respective data points associated with values of the assets, the data points including transaction value information,
- for the data points, determining respective statistical values with respect to a probability density function that fits a power law parameterization to the data points, and
- evaluating a probability function describing the statistical values as a measure of confidence that the probability density function of the data points is validly represented by the power law parametrization.
