RESUMEN
Objective Taking nurses relative number prediction for example,this paper discussed the application of Information Renewal GM (1,1)—Linear Regression Coupling Model in the prediction of health personnel resources,so as to provide methodology reference for forecasting health personnel.Methods The information renewal GM(1,1) and linear regression coupling model was built and explored to predict and fit analyzing.Results The error between the predictive value that calculated by information renewal GM(1,1) and the actual value was small,and the prediction accuracy of coupling model was high.Conclusion The coupling model not only remedied the defect that grey system model did not including linear factors,but also improved the fact that linear forecasting model could not express exponential growth.Therefore the coupling model was reasonable and feasible.
