<P>配合下列模型进行最小二乘方差分析, Y<SUB>ijkI</SUB>＝ µ十P<SUB>i </SUB>+ S<SUB>j</SUB>+ H<SUB>I</SUB>+G<SUB>k</SUB>+ e<SUB>ijkI,</SUB>SAS程序是:</P>
<P>proc glm data=yourdata;</P>
<P>class p s h g;</P>
<P>model y= p s h g/solution type3;</P>
<P>run;</P>
<P>Note: SAS always use the last level(highest level, last letter) as reference, if you need change reference group, you need recode your variables or use dummy variables.</P>
<P>'solution' helps you get all the beta estimations. </P>
<P>Type III test tells you your effects of p, s, h, g are significant or not. </P>
<P>If you need help to read your data, please let me know.</P>
