4 rows while there are a wide range of frequently used quantitative budget forecasting tools, in this. Yt = c+εt +θ1εt−1 +θ2εt−2+⋯+θqεt−q, y t = c + ε t + θ 1 ε t − 1 + θ 2 ε t − 2 + ⋯ + θ q ε t − q, where εt ε t is white noise. Moving averages are averages that are updated as new information is received.
