Figure 1: Identification of the most influential data features based on the logistics regression (LR) model. The bar graph compares observed relative odds ratio of readmissions with 95% confidence interval on the xaxis based on LR model predictions using 39 potential predictors in the training dataset. The 14 most influential data features were selected and plotted as blue bars on the yaxis, and the lengths of the bars represent the relative odds ratios of the individual data features for readmission prediction.
