各位前輩好,想請教前輩一個proc mds的問題!
最近我自己用比小資料,excel匯入SAS練習MDS,
數據如下:

這是類似歐幾里得距離,以下為我寫如語法:
proc cluster data=male method=ward outtree=Tree noprint;
id age;
run;
axis1 order=(0 to 1 by 0.5);
proc tree data=Tree ;
height _rsq_;
id age;
title "1974 male";
run;
proc mds data=male level=absolute out=out noprint ;
id age;
title "1974 male";
run;
symbol value=dot ;
proc gplot data=out ;
plot dim2*dim1=age ;
title "1974 male";
run ;
goption reset=symbol ;
可是是可以跑出MDS圖形,但log中有一句話:
NOTE: 1 observation(s) contained a MISSING value for the Dim2 * Dim1 = age request.
我不懂,
而且GPLOT圖會有一個顏色顯示在標題,但label是空的,圖裡也沒有該顏色的dot
我在想是不是跟log理的note有關!
所以我想請教前輩,這個原因,真的謝謝
