The Study of Cultural Consensus Model Efficiency on Analysis of Differential Rater Functioning: A Simulation Study aimed to: 1) examine the efficiency of parameter estimating of the cultural consensus model, 2) study the factors affecting the model’s efficiency on parameter estimating. The study was conducted in simulation scenario using the Markov chain Monte Carlo simulation method (MCMC).

The study found that: 1) the MC-GCM model could efficiently recover the model parameters. The Pearson correlation coefficient between the true value and the estimated value was statistically significant.  2) The result of MANOVA analysis between the number of raters , number of items  and the differential rater functioning  showed that the differential rater functioning had significant effect on MSE and correlation between the true value and the estimated value.
