DYNAMIC RESEARCH PANEL

摘要

A technique and algorithm for extracting a representative sample from a large, unrepresentative data set through the application of dynamic weighting and random assignment. The algorithm allows for the simple selection of individuals that, as a group, will closely fit any desired ratio of salient variables. The randomization algorithm allows multiple representative groups to be extracted from the same large, unrepresentative data set.

1. A computer-implemented method, comprising:
receiving data for a sample of cases, the cases including at least one variable, each of the cases in the sample of cases having a marker for each of the at least one variable; assigning a weight to each of the cases in the set of cases based on the frequencies among the set of cases for each of the markers of that case, the weight further based on a desired panel frequency for each of the markers; and randomly selecting a subset of cases from the set of cases, wherein the random selection is weighted according to the assigned weights of the users such that, for each of the markers, a frequency of the marker in the selected subset approximates the desired panel frequency for that marker.
