In a forecasting analysis, it is required that higher weightage be given to recent demand information, the smoothening constant for this should be_________

Calculate the difference between 4-week and three-week moving average forecast for 2020

If the previous year forecast was 110 units and actual demand was 115 units, the forecast for current year using exponential smoothening method with smoothening constant equal to 0.3 is _____

Find the ratio of mean forecast error to mean absolute deviation. For the given data _____.

In a forecasting model, the linear regression technique was used for a time series forecasting method which gave the equation: F = 7 + 3t, where F is the forecast for the period. The demand for the five periods of time were 11, 14, 16, 20, 25. The sum of the absolute deviations for the above data is:

For a regression model

∑ x = 36, ∑ y = 5432, ∑ x² = 204, ∑ xy = 26108.8 and n = 8
