From: Local topographic wetness indices predict household malaria risk better than land-use and land-cover in the western Kenya highlands

Figure 1

Change in mean-squared-error resulting from the addition of topographic (white boxes) and land-cover/land-use (gray boxes) variables to predictive models with only a person-time offset. The results of 300 split-sample repetitions are pictured (the box represents the 25th to 75th percentile, while whiskers show range). Negative values indicate that addition of the variable improved the accuracy of the model in predicting malaria risk; boxes crossing the zero line indicate prediction was improved in some random subsets of houses but not in others.
