Radek,
There is a slight problem with Gaussian, Dual-Dirac and DJRJ (more so with
Dual-Dirac and DjRj than with Gaussian).
Dual-Dirac can be expressed in this format: (PDF (Format Dual-Dirac <mean>
<mean> <sigma>)) for ex: (PDF (Format Dual-Dirac 0 0.5 0.01))
and
DjRj in this format: (PDF (Format Dual-Dirac <meanDj> < maxDj > <sigma>)) for
ex: (PDF (Format Dual-Dirac 0 0.5 0.01))
So if you don't specify if its Dual-Dirac or DjRj, the pram input string will
look like this for both:
(PDF 0 0.5 0.01)
How would you know which type of format to apply to PDF.
Thanks,
Ambrish.

Walter,
I do not think we can "remove" Gaussian from the specification. It is already
there.
As a matter of fact we should try to clarify issues like this one, wherever
there is a possibility for misinterpretation.
For Fangyi's question I think the logically correct answer should be the second
one:
(PDF 0.0 0.01)
It follows the concept of (leaf_name value) where "value" in this case
consists of two numbers.

Fangyi,
One of the reasons why I have proposed removing Gaussian as a type in the new
BIRD.

Subject: [ibis-macro] question about Gaussian parameter
Hi, Experts;
If an AMI model has a parameter (PDF (Format Gaussian 0.0 0.01)), what should
the Init input parameter string be? Should it be
(PDF Gaussian 0.0 0.01)
or
(PDF 0.0 0.01)
or other format?
Thanks in advance,
Fangyi
