*Mean Residual | *Mean Residual – Average error for the observations. This can be misleading because the positive and negative errors can cancel. | ||
* Mean Absolute Residual | * Mean Absolute Residual – Mean of the absolute error values for the observations. This is a true mean, not allowing positive and negative errors to cancel. | ||
* Root Mean Squared Residual | * Root Mean Squared Residual – RMS is calculated by taking the sum of the square of the errors for the observations and then taking its square root. This tends to give more weight to cases where a few extreme error values exist. | ||
* Sum of Squared Weighted Residual | * Sum of Squared Weighted Residual – This is the error value that is minimized by a PEST run. | ||
