Log message:
Remove MASTER_SITES= from individual R package Makefiles.

Each R package should include ../../math/R/Makefile.extension, which also
defines MASTER_SITES.  Consequently, it is redundant for the individual
packages to do the same.  Package-specific definitions also prevent
redefining MASTER_SITES in a single common place.

Update to 1.4.30

Upstream changes:
16 June 2017: statmod 1.4.30

- Bug fix to qinvgauss(). In some case the gamma approximation used
  for small right tail probabilities was taking the initial value
  outside the domain of convergence.

27 February 2017: statmod 1.4.29

- rinvgauss() now accurately handles large or infinite values for the
  mean or dispersion.

26 February 2017: statmod 1.4.28

- R_registerRoutines is now used to register the Fortran subroutine

- pinvgauss() and qinvgauss() now use a gamma approximation when the
  coefficient of variation is very small.

17 December 2016: statmod 1.4.27

- qinvgauss() now supports mean=Inf.

Update to 1.4.26

Upstream changes:
28 August 2016: statmod 1.4.26

- Fortran function gaussq2 updated to Fortran 77.

 5 August 2016: statmod 1.4.25

- Add CITATION file.

- pinvgauss() now uses an asymptotic approximation to compute right
  tail probabilities for extreme large quantiles.  This allows it to
  give correct right tail probabilities for virtually any quantile.

- Fix to qinvgauss() to avoid NA values when computing extreme tail
  quantiles where the inverse Gaussian density is subject to floating

- Bug fix to qresiduals() and qresid.invgauss() for the inverse
  Guassian distribution.

Update to 1.4.24

Upstream changes:
 2 February 2016: statmod 1.4.24

- speedup for rinvgauss() by replacing rchisq() with rnorm() and
  rbinom() with runif().

- speedup for qinvgauss() by using qgamma as starting approximation
  for very small right tail probabilities, and inverse chisq as
  starting approximation for very small left tail probabilities.

- qinvgauss() now computes Newton step using log probabilities
  and a Taylor series expansion for small steps.  This improves
  accuracy in extreme cases.  The stopping criterion for the Newton
  iteration has been revised.

- Bug fix to dinvgauss(), pinvgauss() and qinvgauss() which were not
  preserving attributes of the first argument.

30 December 2015: statmod 1.4.23

- qinvgauss() has been improved to return best achievable machine
  accuracy.  It now checks for backtracking of the Newton iteration.

- dinvgauss() and pinvgauss() now check for a wider range of special
  cases.  This allows them to give valid results in some cases
  for infinite or missing parameter values and for x outside the
  support of the distribution.

26 October 2015: statmod 1.4.22

- Functions needed from the stats and graphics packages are now
  explicitly imported into the package NAMESPACE.

Update to 1.4.21

Upstream changes:
30 March 2015: statmod 1.4.21

- qinvgauss() now treats input arguments of different lengths or NA
  parameter values more carefully.

- elda() now gracefully removes structural zeros, i.e., rows where
  the number of cells or the number of assays is zero.

- S3 print and plot methods for "limdil" class now registered.

- Use of require("tweedie") in the qres.tweedie() code replaced by

Log message:
Update to 1.4.20

Upstream changes:
30 May 2014: statmod 1.4.20

- Considerable work on the inverse Gaussian functions dinvgauss(),
  pinvgauss(), qinvgauss() and rinvgauss().  The parameter arguments
  are changed to mean, shape and dispersion instead of mu and lambda.
  The functions now include arguments lower.tail and log.p, meaning
  that right-tailed probabilities can be used and probabilities can
  be specified on the log-scale.  Good numerical precision is
  maintained in these case.  The functions now respect attributes,
  so that a matrix argument for example will produce a matrix result.
  Checking is now done for missing values and invalid parameter
  values on an element-wise basis.  A technical report has been
  written to describe the methodology behind qinvgauss().

- This file has been renamed to NEWS instead of changelog.txt.

- The introductory help page previously called 1.Introduction is now
  named statmod-package.

13 April 2014: statmod 1.4.19

- qinvgauss() now uses a globally convergent Newton iteration, which
  produces accurate values for a greater range of parameter values.

- glmnb.fit() now supports weights.

Update to 1.4.18

Upstream changes:
27 September 2013: statmod 1.4.18
- Update reference for permp().
- bug fix to elda() so that it returns NA for the tests instead of
  giving an error when the Fisher information for the slope isNA.
- Exact roles of authors specified in DESCRIPTION file.
- All usage lines in help files wrapped at 90 characters to ensure
  that code is not truncated in pdf manual.
