In the Amos Data Imputation window, notice that Regression imputation and Stochastic
regression imputation
are disabled. When you have non-numeric data, Bayesian
imputation
is the only choice.
We will accept the options shown in the preceding figure, creating 10 completed
datasets and saving all 10 in a single SPSS Statistics data file called environment-nl-
string_C.sav. To start the imputation:
E Click the Impute button.
The Bayesian SEM window opens along with the Data Imputation dialog box.
E Wait until the Data Imputation dialog box displays a happy face to indicate that
each of the 10 completed data sets is effectively uncorrelated with the others.
Note: After you see a happy face but before you click OK, you may optionally right-
click a parameter in the Bayesian SEM window and choose
Show Posterior from the
pop-up menu. This will allow you to examine the Trace and Autocorrelation plots.
