A Monte Carlo Investigation of Conjoint Analysis Index-of-Fit: Goodness of Fit, Significance and Power.

Peer reviewed

Umesh, U. N.; Mishra, Sanjay – Psychometrika, 1990

Major issues related to index-of-fit conjoint analysis were addressed in this simulation study. Goals were to develop goodness-of-fit criteria for conjoint analysis; develop tests to determine the significance of conjoint analysis results; and calculate the power of the test of the null hypothesis of random data distribution.

Constructing the Exact Significance Level for a Person-Fit Statistic.

Peer reviewed

Liou, Michelle; Chang, Chih-Hsin – Psychometrika, 1992

An extension is proposed for the network algorithm introduced by C.R. Mehta and N.R. Patel to construct exact tail probabilities for testing the general hypothesis that item responses are distributed according to the Rasch model. A simulation study indicates the efficiency of the algorithm. (SLD)
