请问continous的indep variables会有interaction effect吗?
我知道categorical的indep variables要去看下interaction effect是否significant
,但如果indep variable是continous的呢? 有必要或者说理论上允许不允许去看他们
的interaction term啊?
谢谢!!

做regression的时候,如果indep var里面有categorical类型的var,比如
salary=experience+edu+error 里edu是categorical变量,值为1 2 3 ,1代表高中
,2代表大学,3代表graduate school。
那我把它当成数字1 2 3然后直接做regression,得出一个beta值
和我把它变成几个dummy var来做one way anova得出几个fix effect的coefficient
这两种做法,在本质上有啥区别呢? 感觉除了手法上有区别,其他比如predict或者衡
量edu对salary的effect来看,没啥大区别啊?
还有在SAS里coding的话,如果edu的变量类型一开始就定义为categorical的话,那用
proc glm是不是就不需要事先create dummy varible?
请赐教!!

来自主题: Statistics版 - 问个很简单的independent的问题
不indep。但是对于i比较大的时候,近似indep。你这个问题i取值范围多少?
抛开那些个summation不看,其实就是问:
如果X_i indep,那么X_i - X_.是不是indep。这个很显然,对吧。
然后你说,我把i=1,2代入,X_1-X_.和X_2-X_.总是相反,不独立 -.-
另,你说j=1,2。应该是指k=2?

大侠能再具体讲一下log odds的可加性指什么吗
我知道logistics reg本身设计成indep是log odds就是为了能fit出来可加的
Linear sum of indep variables, 但是如果是不同的打分加在一起,还有道理吗,比如
score1 = log (p1/1-p1),
score2 = log(p2/1-p2),
那么score1 + score2 好像不好解释的通啊, 尤其是p1,p2不是independent的两件事情
的话 (虽然比直接p1 + p2多些道理)。
一个引申的问题就是, scorecards model是要把prob 转变成score的,一直不理解转

1099-misc和w2的不同之处是,公司发给自己的employee W2 , 而发给indepent

income已经withhold了social security and medicare tax。而1099-misc的box7上的
数字是没有wihthold social security and medicare tax的。因此irs规定保税人必须
申报这笔收入,并且要上缴没有withold的social security and medicare tax.
