| Abstract: | A change-point problem in finite sequences is considered along with, so-called, k-linear-r-ahead recursive residuals and a test procedure proposed by ?o?a¸d? et al. [?o?a¸d?, J.A., Szkutnik, Z., Majerczak, J. and Duda, K. 1998, Detection of change point in oxygen uptake during an incremental exercise test using recursive residuals: relationship to the plasma lactate accumulation and blood acid base balance. European Journal of Applied Physiology, 78, 369–377.]. Theoretical significance levels of that (conservative) test are compared with its simulated sizes. Numerical approximations to the powers against various alternatives are given. Properties of the k-linear-r-ahead recursive residuals are described and the consistency of the test is proved, when the noise level goes to zero. |
