Multivariable measuring mathematical model is often required in engineering application, least square method is introduced here with the purpose of giving the coefficient parameters of the equation set. Multivariable equation set fitting method is derived on the basis of least square method principle. This method is applied in multisensor measuring calibration and data processing to improve calculating precision. The least square method is compared with normal arithmetic to show its superiority.
