【摘要】 目的探讨采用均数和标准差进行方差分析的方法及SAS程序。方法通过推导,得到基于均数和标准差的方差分析计算公式,并用简洁的SAS程序实现。结果实现了有关算法及SAS程序。结论采用均数和标准差进行方差分析是完全可行的,编制SAS程序可以有效实现相关的计算,得到可靠的结果。
【Abstract】 Objective To investigate an algorithm for analysis of variance(ANOVA) based on mean and standard deviation,and to try to write a SAS program for it.Methods To generate the formulas for ANOVA based on mean and standard deviation through mathematical deduction,and to write a pithy SAS program for the calculation.Results The algorithm for ANOVA based on mean and standard deviation was generated successfully,and a SAS program was developed.Conclusion It is feasible to obtain an ANOVA procedure using mean and standard deviation.Compiling the relevant SAS program is effective and reliabe for the calculation.
