Model selection using the LRT. (Three models, used to describe the spread of PDV in the Dutch Wadden Sea, were compared to see which best fit the data. These models include: homogeneous mixing with uniform β, slight heterogeneous mixing with kβ on the diagonal, and the full stage-structure model with the symmetrical β matrix. The likelihood ratio, degrees of freedom and p-values are listed for each pairwise model comparison. Overall, the model incorporating full stage structure and symmetrical β matrix was the best-fit model to the data.)

models being compared			likelihood ratio	degrees of freedom	p-value	better-fit model
homogeneous mixing with density dependence	v.	slight heterogeneous mixing with density dependence	5.38	1	0.00104	slight heterogeneous mixing with density dependence
slight heterogeneous mixing with density dependence	v.	strong heterogeneous mixing with density dependence	9.63	4	0.000698	strong heterogeneous mixing with density dependence
