gee sas語法、gee範例、SAS GEE在PTT/mobile01評價與討論，在ptt社群跟網路上大家這樣說

[軟體程式類別]:sas

[程式問題]:gee 迴歸

[軟體熟悉度]:低(1~3個月)


[問題敘述]:輸入指令如程式範例範例所示
輸出的結果中,我看不到r-square 及 vif
不知道模型的解釋力如何&是否存在共線性問題
請問我是不是忽略了什麼指令呢?
謝謝^^

[程式範例]:

proc genmod data=try;

class id /desc;

model count_1=id_g1-id_g3 period1 id_g1*period1 id_g2*period1 id_g3*period1
id_sex1 id_age_g1-id_age_g3 id_home1-idh_home3/d=normal;

repeated subject=id/ type=UN;
run;

推 bugle:找vif不需要用到genmod, proc reg就可以了 07/15 21:31
→ minna05:我後來有用proc reg去試跑~只是想知道在gee的報表裡可否 07/15 21:48
→ minna05:呈現....而且沒有r-square讓我很苦惱@@"請大家幫忙囉~ 07/15 21:49
推 bugle:都已經是genmod了，看的都是一些比較進階的東西例如deviance 07/15 21:59
→ bugle:真的非r-sq不可的話就請去找其他regression procedure比較快 07/15 22:00
→ minna05:好的~謝謝指教!所以genmod的語法沒有計算r-square是正常吧 07/16 08:05
推 imaltar:可以看working correlation 07/16 15:17
→ kingbee:不知是否我記錯working correlation 是指重複測量觀察值 07/20 09:51
→ kingbee:之間的關係? 07/20 09:52
→ kingbee:求係數時 所用的working correlation matrix 07/20 10:03
→ kingbee:The method relies on the independence across subjects 07/20 10:07
→ kingbee:to consistently estimate the variance of the proposed 07/20 10:08
→ kingbee:estimators even when the assumed working correlation 07/20 10:08
→ kingbee:structure is incorrect. Zeger (1988), Zeger, Liang, 07/20 10:09
→ kingbee:and Albert (1988), and Liang, Zeger, and Qaqish (1992) 07/20 10:09
→ kingbee:provide further detail on the GEE methodology. (轉貼) 07/20 10:09
