"WitrynaFor a stationary time series, an auto regression models sees the value of a variable at time ‘t’ as a linear function of values ‘p’ time steps preceding it. Mathematically it can be written as −. y t = C + ϕ 1 y t − 1 + ϕ 2 Y t − 2 +... + ϕ p y t − p + ϵ t. Where, ‘p’ is the auto-regressive trend parameter. " - Naive time series
