Description | This paper presents some ideas about comparison of two fundamental linear approaches (AR and ARX models) for modeling RR interval series and its variability recorded in horses during stress-testing. Their theoretical background is discussed in brief and results of some computational experi-ments are given and analyzed, as well. In particular, problems of stationarity, determination of the response to changes of load, estimation of model order are examined here. |
