RE: HP 35s Statistical Distributions Functions
[I am still working on it.
Here is a list of what the current version can do:

Normal distribution:
  • PDF
  • lower and upper CDFs P(x) resp. Q(x)
  • two-sided symmetric CDF A(x) and its complement B(x)
  • quantile function x(p)
Student's t distribution:
  • PDF
  • lower and upper CDFs P(t) resp. Q(t)
  • two-sided symmetric CDF A(t) and its complement B(t)
  • quantile function t(p)
Chi² distribution:
  • PDF
  • lower and upper CDFs P(c) resp. Q(c)
  • quantile function c(p)
Fisher's F distribution:
  • PDF
  • lower and upper CDFs P(F) resp. Q(F)
  • quantile function not yet implemented
In addition, some internal special functions can be used as well:
  • Euler's Beta function B(a,b)
  • Regularized Incomplete Beta functions Ix(a,b) and 1–Ix(a,b)
  • Regularized Incomplete Gamma functions P(a,x) and Q(a,x)

The distribution results are stored in registers A...D, so the user can easily adjust the values that are returned in Y and X.

I just don't know when and if this will ever get finished. ;-)

Dear Dieter
Could you try to publish the F Fisher program individually, while the compile versión is finished?
With my sincere recognition of your hard work, Pedro
