The correct classification rates of each combination of independent variables.
(a) Two independent variables |
| |
4th Vent_vol | Cerebellum_vol | MCP | SCP | Pons | SN | ST | PM |
|
4th Vent_vol | | 0.514 | 0.583 | 0.611 | 0.583 | 0.556 | 0.819 | 0.431 | Cerebellum_vol | | | 0.528 | 0.556 | 0.514 | 0.458 | 0.722 | 0.458 | MCP | | | | 0.708 | 0.472 | 0.667 | 0.833 | 0.528 | SCP | | | | | 0.681 | 0.528 | 0.736 | 0.542 | Pons | | | | | | 0.667 | 0.847 | 0.514 | SN | | | | | | | 0.722 | 0.583 | ST | | | | | | | | 0.653 | PM | | | | | | | | |
|
|
4th Vent_vol: fourth ventricle volume; cerebellum_vol: cerebellum volume; MCP: middle cerebellar peduncle; SCP: superior cerebellar peduncle; SN: substantia nigra; ST: superior temporal region; PM: primary motor region.
