1. A method comprising: obtaining a plurality of actual outcome data points comprising actual outcomes for a plurality of episodes of a process: obtaining a practitioner-independent baseline outcome for said process: for each given one of said actual outcome data points, equating said given one of said actual outcome data points to said practitioner entity-independent baseline outcome multiplied by a plurality of unknown participating practitioner entity outcome indices for each of a plurality of participating practitioner entities, each of said participating practitioner entity outcome indices being raised to an exponent comprising a corresponding one of a plurality of unknown participating practitioner entity type indices, to obtain a plurality of equations; and solving said plurality of equations to obtain estimated values of said unknown participating practitioner entity outcome indices and estimated values of said unknown participating practitioner entity type indices.
