Series J, Gas Furnace Data
Description
Gas furnace data, sampling interval 9 seconds; observations for 296 pairs of data points.
Format
List with ts objects XJ and YJ.
Details
XJ is input gas rate in cubic feet per minute, YJ is percentage carbon dioxide (CO2) in outlet gas. X is the regressor.
Box, Jenkins, and Reinsel (2008) fit an AR(2) to YJ, with transfer function specifications r = 2, s = 2, and b = 3, regressing on XJ. Our package agrees with their results.

fitTF <- arfima(YJ, order= c(2, 0, 0), xreg = XJ, reglist =
list(regpar = c(2, 2, 3)), lmodel = "n")
fitTF ## agrees fairly closely with Box et. al.
