最近看一本讲logistics regression的书,发现以下代码:
ods graphics on;
proc logistic data=Cheese plots(only)=(effect(polybar) oddsratio(range=clip));
freq freq;
class Additive (param=ref ref='4');
model y=Additive / covb;
oddsratio Additive;
title ’Multiple Response Cheese Tasting Experiment’;
run;
ods graphics off;
书上给出了画出的图,但是我的sas9.2怎么没反应啊。它也不报错,但也不画图。我google了一下,说sas/graph在9.2的时候还是需要独立安装,不在base里?谁能告诉我?
