Correlation matrix Note: The correlation coefficient ranges from -1 to 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect positive correlation, and 0 indicates no correlation. Collinearity is typically deemed severe when predictor variables have a correlation coefficient greater than 0.7, as this is assumed to seriously disrupt model estimation and prediction [46]
