Table 3 Summary of validation statistics for predicting continuous PfPR2-10 in Kenya based on a validation set of 210 data points.

From: The risks of malaria infection in Kenya in 2009

Validation measure  
Linear correlation coefficient of predicted versus observed 0.81
Mean error (% PfPR2-10) -0.15
Mean absolute error (% PfPR2-10) 0.38
  1. Mean error is a measure of the bias of predictions (the overall tendency to over or under predict) whilst mean absolute error is a measure of overall precision (the average magnitude of error in individual predictions).
