Can anyone explain in detail how the sporadic forecast is calculated when selected in the Croston method in IBP?
From my understanding reading the PAL documentation, the calculation is similar to standard Croston and fits the smoothing models with parameter alpha for for the Z (estimate of demand volume) and X (estimate of intervals between demand). The last estimate from these smoothing models is then used to create the forecast.
What I’m unsure of is how the forecast is distributed along the future intervals for a sporadic forecast.
