While doing Pre-processing using the Lost Sales Standard Exponential Smoothing method (LS STD ES), the algorithm makes negative adjustments (i.e., negative corrections) to sales values where there is an Out of Stock (OoS) indicator loaded in Retail Demand Forecasting (RDF).

Steps to Reproduce:

  1. Load out of stock indicator into OUTAGE flag, POA set to 'True', and set values for NPTS, NPAST, NFUT.
  2. Run preprocessing using Method Id 9 (Lost Sales ES).
  3. Observe the result for positive spikes; RDF generates negative corrections.
