2.8. Model fitting and comparison
The pore inactivation model has two parameters; K and oil0,
while the linear model only has one parameter; Smax. All models were fitted using nonlinear least squares regression in Excel.
Although the pore inactivation model would be preferred as it rests
on physical phenomena, both models were compared using a statistical
criterion. For this a corrected Akaike criterion was used for
smaller data sets, comparing the models, while taking the different
number of parameters in account
