Abstract
In the GaussMarkov regression model, one can always update the least square estimate of the slope vector, given new observations at the values of the explanatory variables. The updated estimate is often considered as a timevarying state of an autoregressive system in Kalman filtering and recursive least squares theory. This note shows that the autoregressive matrix of this dynamic system once centered has its largest eigenvalues equal to 1 and one eigenvalue that is less than 1.
