The scores for each task have potential scores around 50 or 100, that are not really reachable due to the time allotted. There are theoretically 50 levels on the test--only 19 in the data. Regardless think that is too many for a ordinal logistic model. I will give a zero-inflated count model a go on R and post back on how things work out. Thanks again. | |
