[問題] [SAS] 程式問題 麻煩高手幫我看一下

[magiccat (~米雪~)]

我又來問我
SAS的SYSNLIN 我仿照範例程式寫了一小段作測試
程式如下:
data web_input;
input y_t y_a;
label y_t = 'total cumulative sale'
          y_a = 'apache cumulative sale';
datalines;
18957   658
18864   965
19638   1241
31570   3595
60374   10813
74709   14747
77128   15797
135396  37088
150295  43855
;

PROC SYSNLIN DATA=web_input sur;
MODEL y_t = y_a;
MODEL y_a = y_t;
RUN;

但是在MODEL的地方一直出現錯誤, 麻煩幫我看看, 我問題是出在哪??
(看起來很像因變數的地方有問題y_t, 但是我又不知道是哪裡錯, 要怎樣改)
3Q

錯誤訊息:
444  MODEL y_a = y_t;

推 alias:去看web_input的內容, 你會發現沒y_a 與 y_t這兩個東西
→ alias:因y_t變成了total cumulative sale,解法:去掉label那幾行
推 alias:恩...我錯了, 這樣修改沒用
推 alias:以下為個人沒知識背景的言論(我不熟PROC SYSNLIN):
→ alias:PROC SYSNLIN裡,有MODEL 這指令可用嗎? 因我也看了幾個例子
→ alias:但範例程式裡沒看到像這樣的用法:MODEL a=b;
→ alias:所以,是否再請你去研究一下, 可能會好一些
→ magiccat:謝謝!!我再研究看看
