Subsequently, multiple linear ordinary least square (OLS) regression models were constructed in which potential sociodemographic, lifestyle, and dietary predictors of serum antioxidants (continuous retinol+retinyl esters, total carotenoids, and loge-transformed vitamins E and C) were evaluated with the Wald test.
这是我在看文献的时候看到的方法部分的介绍,据我了解OLS就是普通的多元线性回归(不太确定),那么Wald检验又是怎么和OLS结合的呢,Wald检验一般不是在Logistic回归里面出现的吗?望大家批评和解答!
