Exploring strategies for constructing optimal combined forecasting models for health human resources based on personnel numbers in Anhui Province's healthcare institutions
目的 基于安徽省医疗卫生机构人员数量数据,构建多种卫生人力资源组合预测模型并对比分析,探讨构建最优组合预测模型的策略.方法 于《安徽统计年鉴》获取1988-2022年安徽省医疗卫生机构人员数量数据,使用Holt模型、ARIMA模型、NNAR模型、GM(1,1)和随机森林模型构建所有可能的组合模型,分别预测2018-2022年安徽省医疗卫生机构人员数量,对比各模型的均方误差(MSE)、平均绝对误差(MAE)和平均绝对百分比误差(MAPE)3项误差指标,筛选最优组合模型.结果 在所有的组合预测模型中,GM(1,1)与随机森林模型构建的组合模型预测误差最小,其MSE、MAE和MAPE分别为146 101 146、10 587.465、2.267,该组合模型为最优组合预测模型.结论 选择一定数量的子模型,再通过排列组合的方式生成所有可能的组合模型,并根据误差指标进行筛选,可准确、有效地确定预测误差最小的组合模型.该策略能科学、合理地筛选多种模型,最终得到最优组合预测模型.
Objective To construct and compare various combined forecasting models for health human resources based on personnel number in Anhui Province's healthcare institutions,to explore strategies for developing the optimal combined forecasting model.Methods Data on the personnel number in healthcare institutions in Anhui Province from 1988 to 2022 was obtained from the Anhui Statistical Yearbook.All possible combined models were constructed using the Holt model,ARIMA model,NNAR model,GM(1,1),and random forest model.The personnel number in Anhui Province's healthcare institutions from 2018 to 2022 was predicted.The optimal combined model was selected by comparing 3 error metrics of mean squared error(MSE),mean absolute error(MAE),and mean absolute percentage error(MAPE).Results The combined model of the GM(1,1)and random forest achieved the lowest prediction error among all combined models,with MSE,MAE and MAPE values were 146,101,146,10,587.465 and 2.267,which was the optimal combined forecasting model.Conclusion A certain number of individual models are initially selected,and all possible combinations are generated.These combined models are then evaluated using error metrics to effectively identify the one with the smallest prediction error.This strategy can scientifically and rationally screen various models,ultimately yielding the optimal combined forecasting model.
