This function returns the design matrix for two-group mean estimation. The first column contains indicators for membership in the first group, and the second column contains indicators for memebership in the second group.
twoGroupDesignMatrix(group.one.indices, group.two.indices)indices of observations in group one.
indices of observations in group two.
Returns a design matrix of size n by 2, where n is the sample size.
Example
D <- twoGroupDesignMatrix(1:2, 3:5)
# print(D) displays the following:
[,1] [,2]
[1,] 1 0
[2,] 1 0
[3,] 0 1
[4,] 0 1
[5,] 0 1
