Menu: View→Analysis Properties→Output→Observed information matrix

Place a check mark here to estimate the covariance matrix of estimates by inverting the matrix of exact second derivatives. When Observed information matrix is not checked, the covariance matrix of estimates is estimated by inverting the matrix of expected second derivatives. For more information, see the ObservedInfo method of the AmosEngine class.

Programming

In Amos Graphics programs, you can put a check mark in this check box by using the following statement (Visual Basic):
