Controls whether the covariance matrix of estimates is estimated by inverting the expected second derivatives or the exact second derivatives.
Syntax

object.ObservedInfo (tf)
The ObservedInfo method syntax has the following parts:
Part |
Description |
object |
An object of type AmosEngine. |
tf |
Optional. If tf is True (the default), the covariance matrix of estimates is estimated by inverting the matrix of exact second derivatives. If tf is False, the matrix of expected second derivatives is used. |
Placement: [1].
Default
The matrix of expected second derivatives is used.
Remarks
See Efron and Hinkley (1978) for a discussion of exact versus expected second derivatives in the estimation of the covariance matrix of estimates.
