As a possible solution, statistical methods such as PC analysis are applied in order to construct artificial cluster variables
determined by the implicit weights of a set of microeconomic indicators.
Strata and cluster variables
are publicly available in SIPP data files as GVARSTR and GHLFSAM, respectively (U.
The signs of the coefficients of cluster variables
are as expected, even it it is difficult to compare trends of magnitudes of coefficients.
The cluster algebra is the algebra generated by all cluster variables
, after mutation is repeated ad infinitum.
Furthermore, different types of cluster variables
are used simultaneously in the cluster analyses below.

To determine the conceptual model of measuring innovation for competitiveness (ex post) based on the design of cluster variables
(CDV), which allows the managers of these companies to recognize, evaluate, decide, and implement actions that transform such organizations to be competitive, the study concluded:
Any cluster algebra comes equipped with a distinguished set of generators called cluster variables
which are grouped into finite overlapping subsets called clusters, all of which have the same cardinality.
It is noteworthy that these 10 items represent only five of the 11 cluster variables
and that three variables account for eight of the top ten.

Bivariate correlations between the two industry cluster variables
and the two indicators of economic performance were calculated in SPSS.
Cluster analysis leads to the formation of maximally homogeneous types that are maximally distinct from all other types on the cluster variables
