Using Mplus to Estimate the Log-Linear Cognitive Diagnosis Model
In this chapter, we present the software package Mplus (Muthén LK, Muthén BO, Mplus User’s Guide. 8th edn. Los Angeles, Muthén & Muthén. https://www.statmodel.com/, 2017) with the Log-linear Cognitive Diagnosis Model (LCDM), a general model for diagnostic assessment (Henson RA, Templin JL, Willse JT, Psychometrika, 74(2):191–210, 2009; see also Chap. 8 in this volume). We devote most of this chapter to presenting relevant features of the LCDM as implemented in Mplus with a conceptual example using fraction subtraction data (Tatsuoka KK, Analysis of errors in fraction addition and subtraction problems, Report NIE-G-81-0002. University of Illinois, Computer-based Education Research Library, Urbana, 1984, Tatsuoka C, J R Stat Soc Series C (Appl Stat), 51:337 350. https://doi.org/10.1111/1467-9876.00272, 2002) to illustrate syntax composition, output evaluation, and assessment refinement.
