My most global model outputs a c-hat value of 1.62. As such, I have altered c-hat via the Tools menu. I believe that I also need to inflate my standard errors by the square root of the c-hat.
Is there a way for Presence inflate SEs automatically, or do I need to go through each model and calculate the adjusted SEs manually?
I ask this because the SEs do not presently change when I alter c-hat, but it is implied on p92 of Donovan and Hines (2007) Exercise 4 that they should:
If c-hat was greater than 1, you want to adjust c-hat because many analysts feel that any c-hat estimate greater than 1 potentially biases the standard error estimates. To do this, return to the main menu and go to Tools | Change c-hat.
Then enter the new c-hat value, and click OK. You should see that the standard errors for the different parameter estimates have increased as a result.
Thank you,
