Combined forecast of calibration interval based on linear trend model and LSSVM

A hybrid combined forecast method based on linear trend model and Least squares support vector machine(LSSVM)is proposed to predict the calibration interval of instrument.Integrating linear trend model which has good linear fitting capability and LSSVM which possesses the characteristics of strong nonlinear function approximation,this method has high performance of prediction precision.Real experiments demonstrate that this method outperforms traditional model.
