Model selection for varying MARSS combinations as described in Additional MARSS Modeling Information, MARSS: Model Performance and Selection
| MARSS model formulation | Log likelihood | AIC | Convergence (iterations) |
| Selected model | −1,733 | 3,515 | Yes (35) |
| Remove temperature effect on clarity | −1,762 | 3,571 | No |
| Remove P load effect on clarity | −1,742 | 3,530 | Yes (41) |
| Remove D. pulicaria effect on clarity | −1,736 | 3,518 | Yes (35) |
| Add other grazing zooplankton effect on clarity | −1,733 | 3,517 | Yes (35) |
Models are selected using AIC and previously published ecological interactions.
