If you discover using some techniques which I will describe soon, that your data is basically white noise around a fixed level, then the best that you can do is fit a model around that fixed level. It will be a waste of time to try to do anything better than that. 2. Suppose you have already … See more Let’s again look at the White Noise Model’s equation: If we make the level level L_i at time step i be the output value of the model from the previous time step (i-1), … See more We’ll look at 3 tests to determine whether your time series is in reality, just white noise: 1.
