As far as I can tell, this format "(PDF 0 0.5 0.01)" is not only
questionable in its interpretation, but doesn't it violate
the concept of name/value pair we have in the tree syntax?
If I am not mistaken about that, this seems to be related to
the problem we ran into with the tap coefficients, where one
vendor we all know uses a similar one name, multiple number
format, which might be considered a vector (or array), that
can't be done according to the current official AMI spec.

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.

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
