Is anyone aware of a strategy in Phoenix to eliminate the covariance step. For the purposes of model building I would like to skip this step from time to time to reduce computing time to get parameter estimates? Is this possible?

Hi,

you can turn off the standard error computation by selecting the none option.

In your Phoenix Model Go to Run Options Tab.

Next to the method you have a Stderr: option with the default value being Central Diff.

Click on the arrow and you should have the following options:

none

Central Diff

Forward Diff

 

Select none.

 

Your Phoenix model will not attempt to compute the standard errors after it finishes the estimation.

Bests,
