| Abstract: | A gray model and an unary linear regression model were used in prediction of urban water consumption.The gray model was combined with the unary linear regression model by variance-covariance.Application examples show that the combined model is more accurate than single model,and it can be used in prediction of urban water consumption. |
| Keywords: | variance-covariance combined model water consumption prediction |
