CONT

Model output statistics ... have often taken the form of multilinear regression equations derived by screening potential model-forecast variables as predictors. The method produces forecasts of weather variables that to some extent account for the random and systematic errors in the numerical weather prediction model.

OBS

The difference between model output statistics (MOS) and perfect prognostic is that in MOS the predictand is related to the actual model output, while in perfect prog, the predictand is related to observations or representations of them at (nearly) concurrent times.

OBS

model output statistics: term rarely used in the singular form (model output statistic).
