An Orthogonal Computation Method of Initial Value for Recursive Computing Sensitivities
递推计算灵敏度的初值正交计算法

This paper presents an orthogonal computation method of initial value of sensitivity for maximum likelihood estimation method to he continuous-discrete system. This method is an improvement to the modified Newton-Raphson scheme with estimated sensitivities (MNRES) method. The difficulty to invert the initial matrix in MNRES method is solved by the concept of orthogonal test and orthogonal table
