  This paper focuses on two problems. The first is related to the consistency
checks of the complete correlation coefficients between two groups of variables
obtained in Phys. Lett. B 749, 262 (2015). The first group collects parameters
that describe properties of nuclear matter referring to the transport model
involved. The second one is a group of observables adopted in the heavy ion
collision experiments. The second problem concerns the method of determining
the values of pure correlations between some variables in heavy ion collision.
The application of this method for the analysis of the correlations of the
isospin sensitive variables is pointed out.
