Abstract: Systems and methods are provided for estimating non-sampled store activities by applying projection factors to sampled store activities taking into account restrictions on non-sampled store activities. The systems and methods adjust data projection factors for managed healthcare plans that have restrictions in non-sampled stores to prevent unrestricted activity under these plans at sample stores from being projected into non-sample stores where such projected activity would be restricted. Conventional sampled-to-non-sampled store projection factors leading to restricted plan activities are reallocated to non-restricted plan activities in the non-sample store based on the historical ratio of such activities observed in sample stores.
