I assume that your outcomes are categorical. With categorical outcomes, missing data. and a model without covariates, pairwise present data are analyzed. You can deduce the number of observations used by looking at the covariance coverage output and the missing data patterns that are printed with the PATTERNS option of the OUTPUT command.

I am not sure what this means 'The default is to estimate the model under missing data theory using all available data. To turn on listwise deletion, specify..' (Mplus manual, p.459-60). Does this suggest that all available data are included in the model and path analysis? If I have, say 80 missing values for one variable and 130 for another, how does the system deal with this inconsistent number of missing data for each variable? Does the system use pairwise deletion as a defualt to analyze the path coefficients? Thanks. pat
I am doing a correlation analysis in mplus. According to my data, I decided to use TYPE=COMPLEX and Pairwise deletion, but I didn't find any option to specify pairwise deletion, does this mean it is not provided in mplus?
