be clarified by a simple reparametrization of the regression equation. The present procedure is represented by formula of the form where W is the final physician work
index, C is the inclusion factor, and P is the reference (proxy) compensation index. Suppose the regression prediction is where Xk is the wage index for reference profession k.
This can be rewritten as is a weighted average of the proxy indexes, corresponding to P in the current method. Then a* is the multiplier C corresponding to the current 25%.
