The other four were content validated. [2] However, factor analysis was not used in the development of the test, and many of the scales are highly inter-correlated and ...
The individual's total number-correct score is not the actual score, but is rather based on the IRFs, leading to a weighted score when the model contains item discrimination parameters. It is actually obtained by multiplying the item response function for each item to obtain a likelihood function , the highest point of which is the maximum ...
