**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**

BOOK ANNOUNCEMENT:

'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.
