Summary statistics for both fall risk models using data from the validation gaits.

indicates the model that excludes the long-term Lyapunov exponents, and indicates that the model includes this data. The values are over all of the trials. The root mean squared error (RMSE), mean absolute error (MAE), mean absolute percentage error (MAPE), relative average absolute error (RAAE), and maximum absolute error (Max Abs Err) are given. The % in Tolerance indicates the percentage of these trials in which the predicted value was within the true ln(MFPT)±3.3. The mean SD are the mean of the standard deviation data for each validation condition. The slope, intercept, and are each from a linear fit of the ln(MFPT) for all validation trials (Eq 15). Values of 1, 0, and 1, respectively, would indicate a perfect fit.
