ABSTRACT
Example 8.6.2. Let us analyze the data in Table 8.1 pertaining to 12 double crosses of barley which were raised during 1971-1972 in Hissar, India. The column indices run over different crosses of barley and the row indices run over four different locations. The observation vector has two components, the first being the height of the barley plant in centimeters and the second the average ear weight in grams. Here
det b/det(a+b)=0.4632. Now
is to be compared with F22,64 at a 5% level of significance. Thus our data show there is no difference between crosses.
