Abstract Improving the allocation of external factors in the variations of geophysical fields on the example of the volumetric strain variations is studied. A technique of parameters of the factor model robust estimation, based on the censored sample is shown. Score values of the parameter distortion in the factor model in the case of sequential patterns of removed factors is obtained. On the example of removing the atmospheric pressure and the tidal strain variations in volumetric strain shows the efficiency of the considered techniques.
