摘要
选择了4种常用统计分析软件(SAS,SPSS,DPS和FORSTA),从输入和输出两方面,比较了其中非线性回归的用户界面,从迭代方法、收敛标准、参数初始值选择、计算速度和精度等方面分析了其功能,对其特点进行了评价,并提出了使用时应注意的事项,对用户使用非线性回归模型进行数据处理和分析有指导意义.
Four kinds of statistic softwares (SAS,SPSS,DPS and FORSTAT) have been chosen to compare their user interface of nonlinear regression functions in term of input and output,and to analyse their functions in terms of iteration method,convergence criteria,option of initial value,rapidity and precision. The features of regression have been evaluated and recommendation for users has been put forward, which is useful for data processing and analysis when nonlinear regression model is adopted
