1. A computer-implemented method of predicting by a first computer an output of a target predictive model, the method comprising: (a) receiving, by the first computer from a target model data source maintained by a second computer different than the first computer, a complete set of output data produced as a result of a first run of the target predictive model; (b) receiving, by the first computer from at least one alternate model data source maintained by a third computer different than the first computer, at least one additional complete set of output data, each additional complete set of output data produced as a result of a run of at least one alternate predictive model, wherein the at least one alternate predictive model identifies parameters related to the complete set of output data of the target predictive model; and (c) predicting, by the first computer, a future output expected to be produced as a result of a second run of the target predictive model utilizing a statistical analysis of the complete set of output data from the first run of the target predictive model and the at least one additional complete set of output data from the at least one alternate predictive model, wherein the predicting of the future output expected to be produced as a result of the second run of the target predictive model occurs without the first computer performing runs of the target predictive model and the at least one alternate predictive model, and without observable weather data being used by the first computer in the predicting of the future output.
