The Bayesian model of combined macroeconomic forecasts

There is a wide variety of institutions which periodically publish forecasts about different macroeconomic indexes. Because each source has its own criteria and models, each one commits different errors. Regarding this data, it is reasonable to create a parasitic model which uses various forecasts as input and combine them. In this way, more independent information is obtained and reduces the error of prediction.
