The morbidity of multivariable grey model \(\mathrm{MGM}(1, m)\) (Q1656122)

Summary: This paper proposes the morbidity of the multivariable grey prediction \(\mathrm{MGM}(1, m)\) model. Based on the morbidity of the differential equations, properties of matrix, and Gerschgorin panel theorem, we analyze the factors that affect the morbidity of the multivariable grey model and give a criterion to justify the morbidity of \(\text{MGM}(1, m)\). Finally, an example is presented to illustrate the practicality of our results.
