The importance of interval forecasts is reviewed. Several general approaches to calculating such forecasts are described and compared. They include the use of theoretical formulas based on a fitted probability model (with or without a correction for parameter uncertainty), various “approximate” formulas (which should be avoided), and empirically based, simulation, and resampling procedures. The latter are useful when theoretical formulas are not available or there are doubts about some model…

Prediction Intervals for Time-Series Forecasting
PIs tend to be too narrow because out-of-sample forecast accuracy is often poorer than would be expected from within-sample fit, particularly for PIs calculated conditional on a model fitted to past data.
Model uncertainty and forecast accuracy
Alternative approaches to forecasting, which avoid conditioning on a single model, include Bayesian model averaging and using a forecasting method which is not model-based but which is designed to be adaptable and robust.
Evaluating the Forecasts of Risk Models
An new approach to evaluating interval and density forecasts requires evaluation of the entire forecast distribution, rather than a value-at-risk quantity, which is enough to construct a powerful test even with sample sizes as small as 100.
Prediction intervals for growth curve forecasts
• Mathematics
• 1995
Since growth curves are often used to produce medium- to long-term forecasts for planning purposes, it is obviously of value to be able to associate an interval with the forecast trend. The problems
WK1 Model: Prediction Intervals for Your Forecasts
This paper sets forth a synergy of existing statistical theories to obtain a clear-cut model for calculating forecasts with prediction intervals, named the “WK1 model,” which increases the power of a single discrete point forecast by adding its probable accuracy with top and bottom limits.
