Techniques for Testing the Constancy of Regression Relationships Over Time
TL;DR: In this paper, the stability over time of regression relationships is investigated using recursive residuals, defined to be uncorrelated with zero means and constant variance, and tests based on the cusum and cusume of squares of recursive residual coefficients are developed.

Paper: A survey of design methods for failure detection in dynamic systems
TL;DR: This paper surveys a number of methods for the detection of abrupt changes in stochastic dynamical systems, focusing on the class of linear systems, but the basic concepts carry over to other classes of systems.

On the identification of variances and adaptive Kalman filtering
TL;DR: In this paper, it was shown that the steady-state optimal Kalman filter gain depends only on n \times r linear functionals of the covariance matrix and the number of unknown elements in the matrix.
