Abstract: T he paper expatiated the statisticaLprincipia and their deficiencies of correlation coefficient, stan-dard deviation and variation coefficient most in common use in modeLverification, and for the first time brought forward the conceptions confidence degree and confidence zone of simulated values.Conducted tests orderly with the confidence degree and correlation coefficient between values simulated and actuaLvalues for maize growth and development.
