Box and jenkins approach
WebThe point here is just to demonstrate what ARIMA does. Recall from high school math class that this is the equation for a sine wave: y ( t) = A ∗ s i n ( 2 ∗ π ∗ f ∗ t + ϕ) where: Y (t) means the value of the wave at time t. A means the amplitude, or the peak deviation of the function from zero.
