#### How do I enter a sample covariance matrix?

The olss_cnt dataset (in the Amos Examples directory) shows how to enter a sample covariance matrix along with sample means.

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, .
