"Box and Jenkins furnace data from:
G.E.P. Box and G.M. Jenkins
Time Series Analysis, Forecasting and Control
San Francisco, Holden Day, 1970, pp. 532-533.
There are originally 296 data points {y(t),u(t)}, from t=1 to t=296.
y(t) is the output CO2 concentration and u(t) is the input gas flow
rate. Here we are trying to predict y(t) based on {y(t-1), y(t-2),
y(t-3), y(t-4), u(t-1), u(t-2), u(t-3), u(t-4), u(t-5), u(t-6)}. This
reduces the number of effective data points to 290.
Most methods find that the best set of input variables for predicting
y(t) is {y(t-1),u(t-4)}. Sugeno and Yasukawa has found that the best
set of input variables for predicting y(t) is {y(t-1), u(t-4), u(t-3)}.
The first column below is the output variable y(t), the remaining
columns are the input variables {y(t-1), y(t-2),...u(t-6)}.
