FIGURE 3.

Effect of imputation of SP‐ECog and CBB data. Models having significantly different scores with and without imputation (P < .05) are denoted with an asterisk. No imputation was necessary for models without SP‐ECog and CBB scores, but these were built in parallel with rest as controls; minor differences between paired results for these models are the result of random variation inherent in cross‐validation process. Abbreviations: RF, random forest; SVM, support vector machine; SP‐ECog, study partner–assessed Everyday Cognition score; CBB, Cogstate Brief Battery score; AUC, area under the receiver‐operating characteristic curve
