网络扩展资料
stepwise regression analysis(逐步回归分析)是一种用于建立预测模型的统计方法,它可以通过逐步添加或删除自变量来选择出最佳的自变量组合。这个方法被广泛应用于经济学、医学、生物学等领域。
用法
在进行逐步回归分析时,需要先定义一个因变量和一组自变量。然后,将所有的自变量加入模型中,通过不断计算模型的性能指标(如R²、F值等)来选择最佳的自变量组合。在这个过程中,每个自变量都会被分配一个系数,该系数表示该自变量对因变量的影响程度。最终得到的模型能够用于预测因变量的值。
例句
- The researchers used stepwise regression analysis to determine which variables were most strongly associated with the outcome of the study.(研究人员使用逐步回归分析来确定哪些变量与研究结果最相关。)
- Stepwise regression analysis is a commonly used statistical method in the field of economics.(逐步回归分析是经济学领域中常用的统计方法。)
近义词

- Backward elimination(后向消元):与逐步回归分析类似,但是只能删除自变量,不能添加。
反义词
- Best subset regression(最佳子集回归):一种用于建立预测模型的统计方法,它在所有可能的自变量组合中选择出最佳的组合,而不是通过逐步添加或删除自变量来选择。
