Method for generating data set
First Claim
1. A computer method of generating a probabilistic data set relating to a weather event for use in performing a statistical analysis comprising the steps of:
- a) inputting data representative of an historical track of a weather event, said data including an historical starting point and a plurality of points representative of actual geographical positions along the historical track; and
b) generating data representative of a plurality of alternative tracks based on said historical track, said data including a starting point and a plurality of alternative points, corresponding to said points representative of said starting point and actual geographical positions along the historical track, representative of geographical positions along said alternative tracks;
c) wherein said alternative points are generated from said points along the historical track by a dependent sampling process; and
d) wherein the step of generating data representative of alternative tracks includes the step of limiting a variance of said alternative points from a respective historical point in accordance with one or more physical laws.

Abstract
A computer method of generating a probabilistic dataset relating to a weather event includes inputting data representative of an historical weather event, and generating data representative of a plurality of alternative events. The data for the alternative events are generated, in certain embodiments, by a dependent sampling process. In particular embodiments, the dependent sampling process is a directed random walk process. Data for the alternative events may include data relating to the geographical positions or “tracks” of the event, data relating to atmospheric pressures, or both.
