25 Aug 2020: Statmod 1.4.35
- Fix Bug in tweedie(link.power=0) so that the resulting functions
$linkinv() and $mu.eta() preserve the attributes of their
arguments.
16 Feb 2020: statmod 1.4.34
- Improve the model description provided in the remlscoregamma() help
page.
- tweedie() now checks whether `var.power` or `link.power` are
character strings instead of numeric. If `var.power` is one of the
standard family names ("gaussian", "poisson", "gamma" or
"inverse.gaussian") or `link.power` is one of the standard link
functions ("identity","log","inverse") then the argument is reset
to the corresponding numerical value with a message, otherwise an
informative error message is given.
- Cleaning up of internal code to avoid partial matching of function
arguments, attributes or list component names. The automatic package
tests are now run with the warnPartialMatchArgs,
warnPartialMatchAttr and warnPartialMatchDollar options all set to
TRUE.
4 Jan 2020: statmod 1.4.33
- The components returned by mixedModel2Fit() relating to fixed
coefficients are now documented explicitly. The help page has been
corrected to refer to the argument `only.varcomp` instead of
`fixed.estimates`. The vector of `reml.residuals` is no longer
part of the output.
- The test file has been slightly revised using zapsmall() so ensure
that the test output file remains correct for R with ATLAS BLAS.

The canonical form [1] of an R package Makefile includes the
following:
- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
needed), and CATEGORIES.
- HOMEPAGE is not present but defined in math/R/Makefile.extension to
refer to the CRAN web page describing the package. Other relevant
web pages are often linked from there via the URL field.
This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.

Update to the canonical form of an R package and fix the LICENSE
field.

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.

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
gaussq2.
- 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.

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

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.

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
requireNameSpace("tweedie").

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.

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.
