Missing Data
Graphics Output
Here is the path diagram showing the standardized estimates and the squared multiple
correlations for the endogenous variables:
The standardized parameter estimates may be compared to those obtained from the
complete data in Example 8. The two sets of estimates are identical in the first decimal
place.
Modeling in VB.NET
When you write an Amos program to analyze incomplete data, Amos does not
automatically fit the independence and saturated models. (Amos Graphics does fit
those models automatically.) If you want your Amos program to fit the independence
and saturated models, your program has to include code to specify those models. In
particular, in order for your program to compute the usual likelihood ratio chi-square
statistic, your program must include code to fit the saturated model.
