Abstract
Objective To explore the application of auto regressive integrated moving average(ARIMA) and establish a predictive model for Hepatitis A and,to prove the applicability of the model.Methods Samples which caught Hepatitis A from 1990 Jan to 2007 Dec in Gansu Province were subjected.SPSS Expert Modeler was used to fit ARIMA model,and Q statistic was used to verify the applicability of the model.Results The model of ARIMA(0,1,1)(0,1,1) was established.The statistic of Q was 20.637,which verified the applicability of this model.Conclusion The ARIMA model can be used to analyze the Hepatitis A attack and make a short term prediction.
