序数逻辑回归的解释
我在R中运行此序数逻辑回归: mtcars_ordinal <- polr(as.factor(carb) ~ mpg, mtcars) 我得到了该模型的摘要: summary(mtcars_ordinal) Re-fitting to get Hessian Call: polr(formula = as.factor(carb) ~ mpg, data = mtcars) Coefficients: Value Std. Error t value mpg -0.2335 0.06855 -3.406 Intercepts: Value Std. Error t value 1|2 -6.4706 1.6443 -3.9352 2|3 -4.4158 1.3634 -3.2388 3|4 -3.8508 1.3087 -2.9425 …
