title: [Multi-dimensional evaluation system for schistosomiasis japonica transmission dynamic model].
abstract: OBJECTIVE
  To evaluate the simulation effect of Schistosoma japonicum Cellular Automata (SjCA) model by using the multi-dimensional evaluation system.
  
  
  METHODS
  Several selected indicators, including the Youden index, sensitivity, specificity, accuracy rate and prevalence distance were applied to assess the validity of the SjCA model. The effectiveness of each indicator for model evaluation was compared.
  
  
  RESULTS
  Different indicators in the multi-dimensional evaluation system generated assorted combination of optimized parameters for the SjCA model. The best model according to prevalence distance (99.97%) did not guarantee the ultimate fit when using accuracy rate (79.70%) as the evaluation indicator.
  
  
  CONCLUSIONS
  The multi-dimensional evaluation system is helpful for accurately assessing the simulation results of the discrete stochastic models such as SjCA, and is promising to be universalized to evaluate other similar epidemic dynamics models.
