[程式] sas 迴歸分析
[軟體程式類別]:
SAS
[程式問題]:
迴歸、logistic
[軟體熟悉度]:
中(3個月到1年)
[問題敘述]:
跑multivariate regression時
Y(dependent)=X1 X2 X3...(independent variable or covariate)
主要想問X的部分...
當資料是配對過某些covariate的話,記得之前上課老師有說過
配對的變項是不需要放進去(不知道有沒有記錯...)
想問如果是已利用propensity score配對
最後跑回歸時還需要把covariate都放進去整個model嗎?
還是因為前面已經adjust過,所以其實可不用考慮?
請高手解惑~~
[程式範例]:
之前跑PROC LOGISTIC出現此警告(不太懂...)
WARNING: Some plots have more than 5000 observations and are suppressed.
Specify the PLOTS(MAXPOINTS=NONE) option in the PROC
LOGISTIC statement to display the plots.
