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 x-axis 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 y-axis, and the lengths of the bars represent the relative odds ratios of the individual data features for readmission prediction.
