Dual K-Type Ridge Estimation of Inverse Problem with Morbid Equality Constraints

Abstract

Based on non-precision observation, it researches the inversion problem with morbid equality constraints. And according to the pathological problems exist for the coefficient matrix and the constraint matrix, and it suggests the ridge estimation of the double-k type derived Ridge to determine these parameters. The results show that a variety of programs and double k ridge estimate not only removes the constraint matrix morbid adverse effects, but also can better overcome the master model morbidity and constraint matrix caused by the presence of instability, which is a good estimate.
