| Abstract: | AnnuM grain yield per unit is of random variable characteristic depend on deeply, in view of which the standardized steps autocorrelation coefficient has been adopted as the weight, as well as 26 - year - statistical data as the example. Forecasts and analyzes whether the grain production of Jilin province is abundant or not in the future with the weighting Maerkefu chain model. |
