mortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولPrediction of Agricultural Machinery Total Power Based on PSO-GM(2, 1, λ, ρ) Model
In order to improve the prediction accuracy of agricultural machinery total power then to provide the basis for the agricultural mechanization development goals, the paper used gray GM(2,1) model in the prediction. Through the introduction of parameter λ to correct the background value and parameter ρ for multiple transformation on the initial data, the model was expanded to (2,1, , ) GM λ ρ mo...
متن کاملPrediction of Railway Foundation Settlement Based on the BP Neural Network Model
Based on the method of BP neural network,a foundation settlement of BP neural network prediction model was established for a railway subgrade in HeFei area China. In the model, the previous field monitoring data was used as the training sample and the later settlement was predicted. The model was used for four test sections of the railway subgrade. The results showed that for the four test sect...
