Example 4
Here are the sample variances and covariances:
Warren5v also contains the sample means. Raw data are not available, but they are not
needed by Amos for most analyses, as long as the sample moments (that is, means,
variances, and covariances) are provided. In fact, only sample variances and
covariances are required in this example. We will not need the sample means in
Warren5v for the time being, and Amos will ignore them.
Analysis of the Data
Suppose you want to use scores on knowledge, value, and satisfaction to predict
performance. More specifically, suppose you think that performance scores can be
approximated by a linear combination of knowledge, value, and satisfaction. The
prediction will not be perfect, however, and the model should thus include an error
variable.
Here is the initial path diagram for this relationship:
