发帖数: 61 | 1 有一组数据。Dependent variable yield, independent variables: rate, timing,
form, crop, tillage, year, site. 所有independent variables都是categorical
variable.
我用proc mixed 看这些independent variables 怎么影响dependent variable的：
proc mixed data=st0810;
class year site timing rate form Crop Tillage;
model yield=rate timing form Crop Tillage year;
random site;
lsmeans Nrate nform prevcrop tillage/adjust=tukey pdiff;
run;
我想用结果做5个图：timing, form, crop, tillage, year各做一个图。Y轴是
estimate， x轴是rate。就是想显示这五个变量和rate是怎么样影响yield的。有可能
吗？怎么用SAS来实现呢？
谢谢！ | y*****w

If "rate" is a categorical variable (and yes, you put it in the CLASS
statement), how come you can plot it on an X-axis? To plot a variable on X-
axis, the variable has to be a continuous variable.
Sort out your data first.
