These specific functions are actually part of Octave's core library, not
the Octave Forge statistics package. Are these the particular functions
you are asking about?

Yes, functions that are provided by a loadable package will override
functions that are in Octave's core library.

Packages that are loaded last will override earlier packages. If you
look at a function that is actually provided by the statistics package,
for example 'normpdf', you should see the results you wanted.

There is no simple way to load a package such that its functions do not
override Octave's core library functions. You can try manipulating the
load path directly, or consider not loading the nan package when you
don't want to use it.
