Canonical analysis of subsets Yj with subsets Xi. Relative valuations by squared correlations of the proximities of subsets Xi with subsets Yj. SUCCESSIVE SOLUTIONS
1 | concorgmcano(x,px,y,py,r)
|
x |
is a n x p matrix of p centered variables |
y |
is a n x q matrix of q centered variables |
px |
is a row vector which contains the numbers pi, i=1,...,kx, of the kx subsets xi of x : ∑_i p_i=sum(px)=p. px is the partition vector of x |
py |
is the partition vector of y with ky subsets yj, j=1,...,ky |
r |
is the wanted number of successive solutions rmax <= min(min(px),min(py),n) |
For the first solution, sum_i sum_j \mbox{rho2}(cx_i[,1],cy_j[,1]) is the optimized criterion. The other solutions are calculated from the same criterion, but with orthogonalities for having two by two zero correlated the canonical components defined for each xi, and also for those defined for each yj. Each solution associates kx canonical components to ky canonical components. When kx =1 (px=p), take concorcano function
This function uses the concorgm function
list with following components
cx |
is a n.kx x r matrix of kx row blocks cxi (n x r). Each row block contains r partial canonical components |
cy |
is a n.ky x r matrix of ky row blocks cyj (n x r). Each row block contains r partial canonical components |
rho2 |
is a kx x ky x r array; for a fixed solution k, rho2[,,k] contains kxky squared correlations rho2(cx[n*(i-1)+1:n*i,k],cy[n*(j-1)+1:n*j,k]), simultaneously calculated between all the yj with all the xi |
