Application of Variance Weight Prediction Model in the Output Prediction of Urban Living Rubbish

Urban rubbish has effect on the improvement of urban ecological environment and living conditions, so it is an important social problem, and correctly predicting the future quantity of the living rubbish is the precondition of solving the problem regarding the urban rubbish. This paper, based on relevant statistical data, and setting about from the change regulation of rubbish output, presents common models used for the output prediction of living rubbish, including the multiple linear regression model, GM (1,1) gray prediction model and the exponential model, and establishes the variance weight prediction model by combining the above three models, then designs weight factors according to accuracy of prediction models, the paper, finally achieves predicting results with higher stability and reliability.
