The
olss_cnt dataset
can be found in the file Olss_cnt.txt, and in the
Olss_cnt worksheet of the UserGuide.xls workbook.
You can omit the mean row if
means and intercepts are not parameters of your model.
The following datasets in the Amos
Examples directory also contain sample covariances and
means: Olss_exp, Warren5v, Warren9v, .
