Predicted: The Predicted field indicates whether the estimation algorithm has been successfully executed on the current data.


Error: The Error field shows the difference between the fit and laboratory values in terms of R2.


AEV: The AEV field shows the air-entry value as calculated based on the estimated curve.


Max. Slope: The Max. Slope is the maximum slope (on a semi-log scale) as calculated based on the estimation curve.
