CHIDIM: a FORTRAN program for assessing the dimensionality of binary item responses based on McDonald's nonlinear factor analytic model.
The writers describe CHIDIM, a Fortran computer program for assessing the dimensionality of binary item responses based on McDonald's nonlinear factor analytic model. It is demonstrated that the program calculates the approximate chi-square statistic, which tests the null hypothesis that the off-di...

Tang, K. Linda su: Chi-squared test Statistical software Computer software sug: subj: Chi-squared test Statistical software Computer software ab: The writers describe CHIDIM, a Fortran computer program for assessing the dimensionality of binary item responses based on McDonald's nonlinear factor analytic model. It is demonstrated that the program calculates the approximate chi-square statistic, which tests the null hypothesis that the off-diagonal elements of a residual correlation matrix are equal to zero after fitting an n-factor model to a set of item responses. The use of this program and the interpretation of its results are illustrated through the simulated unidimensional responses of 1,000 examinees on a 25-item test. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
