Figure 3.
Heatmap-style correlation matrix for four variables (COMPINDEX, REGION, INDUSTRY and NO_EMP), with correlations of 1.0 on the diagonal and all offdiagonal coefficients small (between ‒0.1 and 0.3), indicating low pairwise linear associations; a colour scale from blue (‒1) to red (+1) represents the sign and magnitude of the correlations.Correlation matrix of the independent variables
