ABSTRACT
Coefficients aij, i,j = 1, …, N in formula (1) may be calculated using different methods: algebraic, statistical, etc. In (Augutis, Pečiulytė et al, 2012) we proposed to use algebraic method for calculation of these coefficients. This method is quite limited, as we should have square matrices. So, the number of indicators and the number of time moments (when factual values of indicators are observed) must be the same. So, it is better to use Least Square Method (LSM) for calculation of coefficients (Augutis, Krikštolaitis et al, 2013). Let us give the variation for each indicator
