When causal forces are specified, the expected direction of the trend can be compared with the trend based on extrapolation. Series in which the expected trend conflicts with the extrapolated trend are called contrary series. We hypothesized that contrary series would have asymmetric forecast...

Many researchers appear to operate under the impression that causal models lead to more accurate forecasts than those provided by naive models (or “projections”). This study was based on the premise that causal models lead to better forecasts than do naive models in certain situations. The...

The Golden Rule of Forecasting counsels forecasters to be conservative when making forecasts. We tested the value of three of the four Golden Rule guidelines that apply to causal models: modify effect estimates to reflect uncerainty; use all important variables; and combine forecasts from...
