Heatmap from Scientific Research

Pairwise partial Pearson correlation, adjusting for age and sex, between predicted probabilities of COVID-19 vaccination uptake for each test set sample, obtained from each category separately (XGBoost classifiers; the AUCs for these models are shown in Fig. 2a and Supplementary Table 1 ). The colour indicates the strength of correlation, and the correlation coefficient is shown on each heat-map cell. Hierarchical clustering dendrograms of the partial correlation matrix of model predictions are shown beside the matrix and were used in ordering the rows and columns.
