Free, Open and Extensible
ViSta
is Freely Redistributable.
-
This
means that ViSta is not in the public domain, but that it may be freely
copied and redistributed, with the restrictions noted in the copyright
notice.
ViSta is an OPEN software system
- All of the code is available to the programmer. This includes both the
Lisp code for ViSta and the C
code for XLisp-Stat.
- This code can be used as the basis for developing new code that extends
the system's capabilities.
Open, but with moderation!
- ViSta
5.5 is being distributed with a moderated open source policy. Rather
than distributing the sources with the standard download, the distribution
is being moderated by the developer. If you need access to the source code
you must obtain the password from Forrest
Young.
ViSta is an EXTENSIBLE software system
- Programs written in Lisp, FORTRAN or C are accessible from
within ViSta.
- New model-objects can be written to extend the range of desired model-objects
that perform major, "prepackaged" statistical computations.
- New graphical-objects can be written to implement new statistical graphics
ideas.
