Abstract. A method for choosing the best regression model for the cases when the measuring task is associated with the study of the stability of the metrological characteristics of the calibrated measuring instrument is described. A description of the experiment set up when using this method in the course of researching the metrological characteristics of measuring instruments for the numeric concentration of light air ions is given, and the research results obtained using this method are given.

Keywords: regression model, stability of measuring instruments, calibration of measuring instru­ments, calibration characteristic, light air ions, counting concentration, ionized air, air ion counter.
