Re: [問題] logistic regression model
※ 引述《forever0322 (水藍色)》之銘言：
想請問SAS logistic regression model
跑出來的beta0和beaa1值和我用minitab和SPSS差正負號
檢查蠻久也是找不出來
PROC IMPORT OUT= book1 /*this is the name of the data set*/
DATAFILE= "I:\123\book1.xls" /*this is where you saved your excel data file*/
DBMS=EXCEL REPLACE;
SHEET="sheet1"; /*sheet1 is the excel files sheet name*/
GETNAMES=yes; /*yes means the first row of the data is the variables names*/
RUN;
proc LOGISTIC ;
MODEL Y = X ;
run;
這是SAS的程式碼
我這樣KEY有錯嘛?
麻煩是否可以給我指正
拜託大家了
謝謝

用回的好了
你用同樣的資料跑兩種code
1. proc logistic;
order=internal;
model Y=X;
run;
2. proc logistic;
order=internal desc;
model Y=X;
run;
這兩個應該會跑出剛好相反的beta值
第一個是fit P(Y=0|X)
第二個是fit P(Y=1|X)
看看那個是你要的吧
