I would like if possible to carry out tests of local independence
between pairs of reading test items (i.e., the probability of getting a
correct response on one item should be independent of a correct response
on another item within a passage). The only method that I have found so
far is cumbersome in that it involves no less than three test item
analysis software packages. There is a test which computes the
correlation between residuals of pairs of items but again after a search
on SPSS home page I cannot find anything that appears to be analagous to
Has anyone carried out such a test in SPSS?
Thanks in adavance.
