四、dummy variable 在logistic回归中,经常会遇到解释变量为分类变量的情形,比如收入:高、中、低;地域:北京、上海 、广州等。这里对分类变量而言就涉及一个问题:要不要将分类变量设置dummy variable? 这个问题的答案在线性模型中很显然,必须要这么做!!!如果我们不设置哑变量,而是单纯地赋值:北 ...

R中输入数据类型有两类,R mode和Q mode。一般来说数据每一列为一个变量(variable),每一行为一个数据(observation)。其中R mode的数据行数大于列数,是基于变量的分析;Q mode数据列数大于行数,是基于数据的分析。 Princomp和prcomp都是R自带的stats包中的函数。Princomp只能用于R mode,它基于协方差(covariance) ...
