Abstract:We selected several factors affecting the Birth Rate in Guangdong Province. Then we saw the contribution of each characteristic to the Birth Rate by the gradient boosting regression tree model. The grey prediction algorithm used each characteristic to predict its value in a certain year. Using variance ratio and small residual probability, we evaluated the prediction accuracy. We used the gradient boosting regression tree for predicting the Birth Rate in the next two years. This was done under the premise of k… Show more
