Spearman correlation of the complete CFAS neuropathological data set. Heat map of Spearman correlation coefficients between 34 neuropathology features in addition to age and brain weight features as a benchmark, 36 features in total and 186 samples. A coefficient close to 1 (blue colour) means a high positive correlation between the two variables. The diagonal line is the same variable, i.e. Spearman rho 1
