Dear all,
TAKE X1,X2 and X3, 3 variables and n observations, forming a matrix (data
frame, nx3).
One can use Compositional Data analysis if X1+ X2+ X3=constant (sum min rows),
say K, for each observation.
Does anyone know any statistical analysis (or reference books/papers) method that should be performed if for each variable (X1,X2,X3), the sum (sum in colun) over all observations is equal to the same constant, say C?
Thank in advance,
Alphonse
