Abstract :
Time series data for blood hemoglobin and plasma protein observed in 31 chronic hemodialysis patients for periods of three to seven years were analyzed by Akaike´s method of multivariate autoregressive modeling. The results of the analysis were rather uniform among the patients and suggested that this approach can consistently identify the dynamic system of individual patients
