Hello, can someone please tell me how to specify an inverse gamma prior?
Suppose I know that the technology shock has a standard deviation around 0.007 for a quarterly model.
What parameters should I input in the "stderr ea, inv_gamma_pdf" command if I want to attach more probability mass to my guess about the standard deviation?
What is the difference between inv_gamma1_pdf and inv_gamma2_pdf?
Can you point me to some reference where I can read more on this?
I would be very grateful!
