Current computations of commonly used fit indices in structural equation modeling (SEM), such as RMSEA and CFI, indicate much better fit when the data are categorical than if the same data had not been categorized.

To estimate structural equation models, researchers generally draw on two methods: covariance-based SEM (CB . When modeling with regression, a researcher reports an R 2. Fit indices are easily biased and demonstrate considerable variability.

The use of sample covariance matrices constructed with pairwise deletion for data missing completely at random (S PW) is addressed in a simulation study based on 3 sample sizes (n = 200, 500, 1,000) and 5 levels of missing data (%miss = 0, 1, 10, 25, and 50). It has received 1749 citations till .
