| Abstract |
In this column we demonstrate with a simulated example the problem of spurious regression for autocorrelated data. This is another problem quality engineers may encounter when investigating possible input-output relationships. For example, suppose the process is an industrial furnace and we want to see if there is a possible relationship between an input variable xt, such as fuel rate at a given time t, and the temperature yt in the furnace. |
