- 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.
30 January 2013: statmod 1.4.17
- new function eldaOneGroup() to conduct limiting dilution analysis
when there is only one treatment group. This function implements
a globally convergent Newton iteration to avoid occasional problems
with lack of convergence of the usual glm calculations.
- elda() (aka limdil) now call eldaOneGroup() to get confidence
intervals and score tests. This improves the numerical reliability
of the function.
- more detail added to the elda() help page about the interpretations
of the goodness of fit tests.
- new function forward() for forward selection in multiple regression
with an unlimited number of candidate covariates.
- license upgraded to GPL from LGPL.
28 September 2012: statmod 1.4.16
- gauss.quad() and gauss.quad.prob() now use Fortran to solve
tridiagonal eigenvalue problem, with considerable gain in speed.
Updates to references for the same two functions.
- Formatting of gauss.quad test output to ensure agreement between
Unix and Windows.
- mixedModel2 test code no longer prints REML residuals, because
these are not reproducible between Windows and Unix.
6 August 2012: statmod 1.4.15
- improvements to glmnb.fit() to make it more numerically robust.
- use of lgamma() in gauss.quad() to avoid floating overflows
with kind="jacobi".
19 November 2011: statmod 1.4.14
- power.fisher.test() now accepts a new argument alternative
which indicates the rejection region.
25 October 2011: statmod 1.4.13
- bug fix to glmnb.fit() when dispersion is a vector argument.
18 October 2011: statmod 1.4.12
- glmnb.fit() now accepts vector dispersion argument.
- change to residual returned by tweedie glms when var.power=2
and y==0. In this case the theoretical residual is -Inf.
The value returned by the tweedie family is finite, but smaller
than previous.
29 June 2011: statmod 1.4.11
- updates to help page for sage.test
21 April 2011: statmod 1.4.10
- bug fix to glmnb.fit().
9 March 2011: statmod 1.4.9
- bug fix to glmnb.fit().
- bug correction to sage.test() when library sizes are equal.
The p-values returned change slightly.
3 November 2010: statmod 1.4.8
- new function glmnb.fit(), which implements Levenberg-modified
Fisher scoring to fit a negative binomial generalized linear
model with log-link.
28 May 2010: statmod 1.4.7
- permp() now has two new arguments 'method' and 'twosided'.
The function now provides both exact and approximate methods
for computing permutation p-values.
19 April 2010: statmod 1.4.6
- psi.hampel() and rho.hampel() renamed to .psi.hampel and
.rho.hampel and removed from export function list.
16 April 2010: statmod 1.4.5
- new function mscale() which is the robust estimation of a scale
parameter using Hampel's redescending psi function.
- new function psi.hampel() which is the Hampel's redescending psi
function.
- new function rho.hampel() which is the integral of Hampel's
redescending psi function.
30 March 2010: statmod 1.4.4
- remlscore() now returns a component iter giving the number of
iterations used.
18 February 2010: statmod 1.4.3
- new function permp() which calculates exact p-values for
permutation tests when permutations are sampled with replacement.
5 January 2010: statmod 1.4.2
- new argument 'dispersion' for glm.scoretest(), allowing the
user to set a known value for the dispersion parameter.
- ensure chisq values from limdil() remain positive, even when small.
- correct the format of chisq value in print.limdil().
29 Sep 2009: statmod 1.4.1
- fixes to documentation links to other packages
- bug fix to glmgam.fit() when there are exact zeros
in the data or fitted values.
- add more goodness of fit tests to elda().
- improvements to print.limdil method.
- argument log added to dinvgauss(), giving the option of
returning the density on the log-scale.
6 May 2009: statmod 1.4.0
- new function glm.scoretest() to compute likelihood score tests
for terms in generalized linear models.
- Improvements to elda() and print.limdil() to avoid glm fits in
extreme data situations with 0% or 100% positive response,
improving speed and avoiding warnings.
- Improvements to print.limdil method.
- New function .limdil.allpos(). It calculates lower bound of
the limdil confidence interval when all tests respond by using
a globally convergent Newton interation.
- Modify limdil() on lower bound of the confidence interval when all
tests respond.
- New methods print.limdil and plot.limdil for limdil objects.
- The output from limdil() is now a limdil class object.
- Added \eqn{} markup to equations in pinvgauss.Rd
remlscor.Rd and remlscorgamma.Rd.
- Elso et al (2004) reference added to compareGrowthCurves
help page.
18 November 2008: statmod 1.3.8
- qres.nbinom now works in more situations. It now accepts
a model fit from MASS::glm.nb or a model fit using
MASS:negative.binomial() when the theta argument is unnamed.
Previously the theta argument had to be named, as in
negative.binomial(theta=2).

no cells responds or all cells respond to all tests in one of the groups.

multiple experiments or groups.
