Product Summary: This software release contains Python functions for weighting multiple non-independent estimates of a variable. Weighting is determined by the standard error of prediction of each estimate and the correlation between the estimation methods. The methodology for weighting estimates from either two or three different methods is described in Chase and others (2020). A function is also included to handle four different estimates by discarding the estimate with the greatest standard error of prediction and weighting the other three estimates using the methodology of Chase and others (2020).
