ESTIMATION OF PARAMETERS IN ONE CLASS OF NONNEGATIVE LINEAR PROCESS
一类正值线性过程的参数估计

A class of general non-negative linear process is proposed.The procedure of estimating its(in particular,ARMA(p,q),s)parameters is made by solving a group of linear equations.The strong consistency of estimators is obtained.Finally some open problems are presented andwill be solved in another paper.
