To obtain a submatrix of B corresponding to the w_j group.
Usage
get.bj(c, B, p, j)
Arguments
c
An integer scalar with the desired number of groups.
B
Matrix B.
p
The total number of varialbes of input data matrix.
j
The group index number.
Value
A matrix with the first column vector is the j column vector of matrix B, the second column vector is the j+p column vecotr of B, ... the nth column vector is the j+(n-1)p column vector of B. And j<=p*(c-1). this="" new="" returned="" value="" corresponds="" to="" the="" w_j="" group.="" <="" dl="">
