Subject: Inverses of Distribution Functions

A colleague raised the following question:

For a statistics toolbox I am currently implementing, I would need
"direct" algorithms for computing the inverses of the normal, gamma
and beta distributions functions (or equivalently, for the INVERSES of
the error function
erf(x) = \int_0^x exp(-t^2) dt,
the incomplete gamma function
gammai(a, x) = \int_0^x (exp(-t) * t^(a-1) / gamma(a)) dt,
and the incomplete beta function
betai(a, b, x) = \int_0^x (t^(a-1) (1-t)^(b-1) / beta(a,b)) dt.

By "direct" I mean anything which avoids solving an equation f(x) = y
(series expansions, continued fractions, ...)

Could anyone point out helpful references?

Subject: Request for Peters/Wilkinson Eigenvalue Code

I would like a copy of the Fortran source for the program described in
"Eigenvalues of Ax=Lbx with band symmetric A and B" by Peters and
Wilkinson, Comp. Jour. 14(1969) pp.398-404. I once had a copy on cards
but it did not survived several moves. I have had requests for routines
to solve this problem, and I think it belongs in the TOMS collection
using the LAPACK array storage format(s). Although it was designed for
positive definite B, I believe it will work for more general cases with
simple modifications.

Subject: New Book, Lattice Methods for Multiple Integration


Ian H. Sloan and Stephen Joe
Oxford University Press, New York and Oxford 1994.
ISBN 0-19-853472-8
250 pages, 60 line figures
Price: $US55

Orders from OUP Customer Services, 2001 Evans Road, Cary, NC 27513,
phone 800-451-7556 fax 919-677-1303.

This book is the first devoted to lattice methods, a recently developed
method for the evaluation of multiple integrals in many variables, which
arise in quantum physics and chemistry, statistical mechanics, Bayesian
statistics, and many other fields.

The book begins with a review of existing methods, before presenting lattice
rules in a thorough self-contained manner, with numerous illustrations and
examples. Group theory and number theory enter the story, but the treatment
is such that no prior knowledge of these subjects is required.

Both the theory and practical implementation are covered. An algorithm is
presented along with tables not available elsewhere, allowing the practical
evaluation of multiple integrals in up to at least 12 variables. Most
importantly, the algorithm produces a very efficient estimate of the error.

The book provides a fast track for readers wanting to move rapidly to using
lattice mathods in practical calculations. It concludes with the results
of extensive numerical comparisons with other methods, such as the
Monte Carlo method.
