Retraction Notice: Coupled Model and Algorithm of Spatial Partition Based on Multiple- Factor

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...

Spatial Clustering Algorithm Based on Hierarchical-Partition Tree

In spatial clustering, the scale of spatial data is usually very large. Spatial clustering algorithms need high performance, good scalability, and are able to deal with noise and multidimensional data. In this paper, we propose a rapid spatial clustering algorithm based on hierarchical-partition tree. The proposed algorithm partitions spatial data into subsets by simple arithmetical calculation...
