摘要
应用GARCH模型理论分析某医院2003年至2012年月门诊量变化趋势,并建立AR(1)-IGARCH(2,1)模型,比较2003年至2012年月门诊实测值和模型预测值,其平均相对误差为0.057%,然后应用AR(1)-IGARCH(2,1)模型预测了2013年和2014年该院的月门诊量,比较2013年1月至6月月门诊量实测值和模型预测值,其平均相对误差为0.67%。分析结果表明GARCH模型能很好地追踪门诊量变化趋势。
To analyze the change trend of the monthly outpatient numbers from 2003 to 2012 of a hospital using the GARCH model theory, and build an AR (1) - IGARCH(2,1) model, then compared the actual numbers and the forecast numbers from 2003 to 2012, the average relative error is 0.057%. To forecast the monthly outpatient numbers of the following 2 years with the applica- tion of AR (1) - IGARCH (2, 1) model, and then compare the actual numbers and the forecast numbers date from January to June in 2013, the average relative error is 0.67%. The result indicated that the GARCH model was a good tool in closely tracing the change of monthly outpatient numbers.
