The example in Exhibit 1 of the chapter and the associated discussion are part of
my longstanding and fervent plea to avoid the use of structural equation methods.
In addition to the data demonstrations here, more technical treatment of this theme
is given in
Rogosa, D. R. (1993). Individual unit models versus structural equations: Growth
curve examples. In Statistical modeling and latent variables, K. Haagen,
D. Bartholomew, and M. Diestler, Eds. Amsterdam: Elsevier North Holland, 259- 281.
To augment Exhibit 1 we provide here
- Exhibit 1 data, 40 observations in both Xi(t) and X(t) versions
- Data analysis consisting of Minitab descriptive analyses, scatterplots,
and regressions, some of which are presented in the chapter.
