Assessing Forecast Accuracy: Be Prepared, Rain or Shine - iSixSigma
Apr 28, 2010 · Forecast horizon describes how far into the future a metric is forecast. For example, weather forecasts typically have a horizon of up to 10 days. Forecast bias measures how much, on average, forecasts overestimate or underestimate future values. For example, a sales forecast may have a positive (optimistic) or a negative (pessimistic) bias.
Making Sense of Time Series Forecasting - iSixSigma
Jul 31, 2010 · Another potentially confusing element of the linear trend plot is the forecast accuracy measures: MAD, MAPE and MSD. These are used to determine how well the trend will accurately predict the future volume. MAD. MAD stands for mean absolute deviation, which is the average of the absolute deviations.
Improved Forecasting with Moving Averages and Z-scores
Feb 26, 2010 · Although this percentage can be found by using a software program, the manual calculation is almost as easy. A Black Belt can calculate the same percentage by using the Z-score and referring to a normal distribution table. In this example, where z (number of s a value represents) = (216 – 203) / 13 = 13 / 13 = 1.
