The systematic error correction in measurement transduction of the physical quantities X, X2 and X3

The paper develops the theory of correcting the systematic errors for the care with measurement and calculation transduction of physical quantity X into X, X² and X³ under the nonlinear function of sensor or measurement transducer. The paper enumerates the problem for the systematic error correction theory at which the scientists´ efforts should be directed. The systematic error correction algorithms are derived and represented for some special cases with the transfer functions. Also, the paper discusses the theoretical and practical problems of implementing the directional effects method i.e. the generalized systematic error correction one
