The unit for the estimated conditional expected value of given
, j in
and
and the estimated covariance matrix of
given
, j in
, and
for each examinee i. In listening1.txt, uniteapskill is not specified and takes its default value of 10. In this case, no request is ever made for the transformed EAP values, for the dimension of the
is 1. In threefacte.txt, transformed EAP values are requested. Here uniteapskill is 11. The corresponding file is threefacteapskill.csv.
