(math/R-VGAM) Updated 1.1.1 to 1.1.6
CHANGES IN VGAM VERSION 1.1-6
NEW FEATURES
o Most of the GAIT regression code have new arguments 'd.mlm'
and 'd.mix' but mainly only the dpqr-type functions work!
Some other functions should work such as gaitdpoisson() and
dgaitplot(). Also, is.deflated() and goffset() are new.
o New family function: gaitdnbinomial().
o Upgraded family functions: gaitpoisson() becomes gaitdpoisson(),
gaitlog() becomes gaitdlog(), gaitzeta() becomes gaitdzeta().
o New generic and/or methods functions: KLD(), Pheapseep().
o Some colours are pre-defined for GAITD regression, and the default
colour scheme has changed.
o trim.constraints() has a new 'intercepts = TRUE' argument.
o Many family functions have a 'dpqrfun' component in the @infos slot.
Useful to tie in the modelling function with its density, etc.
o binormal() has a new 'rho.arg' argument.
o Some link functions handle deriv = 4: e.g., loglink(), logitlink().
o vglmfit@misc$history gives the convergence history.
o Improvements to clogloglink() at the boundary 1.
o hdeff.vglm() has a new argument 'theta0'.
o wald.stat() cleaned up internally.
o Tested okay on R 4.1.2.
BUG FIXES and CHANGES
o All GAIT regression code has arguments 'alt.mlm' changed to
'a.mlm', 'inf.mix' changed to 'i.mix', etc. Colours have changed.
[dpqr]gaitpois() have been renamed to [dpqr]gaitdpois(),
and gaitpoisson() to gaitdpoisson().
o [dpqr]zanegbin() no longer supports argument 'prob'.
o hdeff() makes a recursive call if any NAs are in the answer and
fd.only == FALSE. So the answer should then be a 'proper' one.
o Code involving anova() for VGLMs/VGAMs changed to avoid an
error when loading in \pkg{semTools}.
o spikeplot(..., use.table = TRUE) failed wrt x.use and y.use.
o vcov() slightly faster for "vglm" objects. Thanks to Frank Harrell
for comments that led to this.
o linkfun.vglm() changed to linkfunvglm().
CHANGES IN VGAM VERSION 1.1-5
NEW FEATURES
o New functions: meangait(), spikeplot(), trim.constraints().
o iam(i, 1:M, M = M) now works, for selecting a whole row,
and similarly for a column.
o Tested okay on R 4.0.3.
BUG FIXES and CHANGES
o gait[log,poisson,zeta](): arguments llambda.[ai] and lshape.[ai]
equal llambda.p and lshape.p by default. This means only one
argument needs be assigned in order to change them all.
o [dpqr]genpois[12]() has argument 'mean' changed to 'meanpar'.
o gait[log,zeta]() bug fixed wrt missing 'allprobs'.
o qfoldnorm() now uses the bisection method. Thanks to
Mauricio Romero for a suggestion that led to this.
o gait[log,poisson,zeta]() compute the sandwich formula
explicitly for the working weights; this has speed gains.
Their @deriv avoids nested for() loops too.
Their initial value grids have become coarser.
o Functions moved to VGAMdata 1.1-5: yip88, bellff(dr), tikuv(dpqr).
CHANGES IN VGAM VERSION 1.1-4
NEW FEATURES
o Functions score.stat() and wald.stat() offer greater flexibility
by some new arguments, and 'as.summary' changed to 'orig.SE'.
o Influence() computes the influence functions of a "vglm" object.
o Methods functions hdeff.matrix() and hdeff.numeric() are new.
o Family function slot genpoisson()@ weight was updated with
the EIM derived by Easton Huch, and after major changes,
genpoisson() was renamed to genpoisson0().
o New functions: [dpqr]gaitnbinom(), [dpqr]gaitgenpois[012](),
[dpqr]gaitbinom(), dgaitplot(), plotdgait.vglm(), Trunc().
o New family functions: genpoisson[12](dpqr), gaitpoisson()
so that gaitpoisson.mix() and gaitpoisson.mlm() were removed,
gaitlog() so that gaitlog.mix() was removed,
gaitzeta() so that gaitzeta.mix() was removed.
o Tested okay on R 4.0.3.
BUG FIXES and CHANGES
o Deprecated: dgenpois(), genpoisson(), [dpqr]gaitnbinom.m[ix,lm]().
gatnbinomial.m[ix,lm](dpqr), [dpqr]gaitbinom.mlm(),
gaitpoisson.mix(), gaitpoisson.mlm(), gabinomial.mlm(),
gtbinomial().
o 'lhs.prob' changed to 'cdf.max.s'.
o Argument changes for all GAIT code, e.g., 'alter' changed to
'alt.mix' or 'alt.mlm', 'byrow.arg' to 'byrow.ai', etc.
o Functions moved to VGAMdata 1.1-4: oalog, oilog, otlog,
oapospois, oipospois, otpospois, oazeta, oizeta, otzeta, oizipf,
oiposbinomial(dpqr), [dpqr]posbinom, [dpqr]pospois, [dpqr]posnegbin.
o Pearson residuals no longer printed by default in a summary
of a "vglm" object: presid = FALSE.
o Some changes made to plot(vgam()) code for changes in R 4.0.0,
especially if the covariate is a character/factor.
Now avoids "coercing argument of type 'double' to logical" warning.
o negbinomial(lmu = "nbcanlink") had an error relating to "newemu".
CHANGES IN VGAM VERSION 1.1-3
NEW FEATURES
o New functions: [dpqr]gaitpois(), [dpqr]gaitlog(), [dpqr]gaitzeta(),
dextlogF().
o New family functions: gatnbinomial.mix(dpqr),
gaitlog.mix(dpqr), gaitpoisson.mix(dpqr), gaitpoisson.mlm(dpqr),
extlogF1(d).
o New generic and/or methods functions: altered(),
inflated(), truncated(), specialsvglm(),
fix.crossing(), is.crossing().
o Coef.vlm() handles models with contiguous "multilogitlink"s,
e.g., gaitpoisson.mlm().
o get.offset() is now defined as a generic function (returns the
n x M matrix of offsets by default).
o Some .f files have been pruned of unnecessary code.
o New data set: V2.
o Tested okay on R 4.0.0.
BUG FIXES and CHANGES
o Another attempt to .Deprecated() all link function names
which do not end in "link", e.g., loglink() replaces loge(),
logitlink() replaces logit().
o gatpoisson.mix() (now merged into gaitpoisson.mix())
reorders its linear/additive predictors and now handles
length(alter) == 0 (default, so equivalent to poissonff())
and length(alter) == 1.
Ditto for gatnbinomial.mlm(), etc.
o Three argument mismatches found in .f and .c code.
o qlog() and qyules() buggy wrt interval selection prior to
applying bisection.
o 'Rank mismatches' flagged by gfortran10 fixed, by not
calling two subroutines.
o [dpqr]gaitpois.mlm() and [dpqr]gaitpois.mix() have been combined into
[dpqr]gaitpois().
CHANGES IN VGAM VERSION 1.1-2
NEW FEATURES
o New generic and/or methods functions: add1.vglm(),
dfterms(), drop1.vglm(), extractAIC.vglm(),
rootogram4vglm() [based on \pkg{countreg}],
step4vglm().
o New family functions: gabinomial.mlm(), gatnbinomial.mlm(dpqr),
gatpoisson.mix(dpqr), gatpoisson.mlm(dpqr).
o New functions: [dpqr]zipfmb(),
[dpqr]gaitbinom.mlm(), [dpqr]gaitnbinom.mlm(),
[dpqr]gaitpois.mlm(), [dpqr]gaitnbinom.mix(),
[dpqr]gaitpois.mix().
Note that the naming conventions have changed somewhat, especially
regarding the negative binomial distribution.
o Decommissioned functions:
gapoisson(), gtpoisson(),
[dpqr]gabinom(), [dpqr]gapois(),
[dpqr]gibinom(), [dpqr]gipois(),
[dpqr]gtbinom(), [dpqr]gtpois().
o eta2theta() should be able to handle links for, e.g.,
gatpoisson.mlm(), gibinomial().
o posbernoulli.t() has a 'type.fitted' argument.
o gtpoisson.mlm() supports type.fitted = "Pobs.a",
gipoisson.mlm() supports type.fitted = "Pstr.i".
o New data set: backPain2.
o Cleve Moler added to DESCRIPTION as a contributor, to reflect
the use of LINPACK.
o Tested okay on R 3.6.1.
BUG FIXES and CHANGES
o Use of old link function names now result in a call to
.Deprecated(), except for a selected few such as logit() and
probitlink()---this will only be allowed for a limited time.
o negbinomial()@initialize bug fixed for "nbcanlink()" and
multiple responses; thanks to Victor Miranda.
o cens.poisson() gave a warning upon a summary().
Thanks to Jens Heumann for picking this up.
o bisection.basic() returns a warning, not an error, if
it cannot find an interval which covers the root.
o Rank() has an improved implementation and documentation.
o anova.vglm() had some bugs---thanks to Thamron Keowmani for
finding them.
o posnormal() failed when 'constraints' was inputted---thanks
to Michael Zamo for picking this up.
o Improvements to yules(dq).

Update to 1.0.5
Upstream changes:
CHANGES IN VGAM VERSION 1.0-5
NEW FEATURES
o extlogit() now handles 'deriv = 3'.
o Generic function hdeff() implements an analytic solution
for the following families: borel.tanner(), felix(), lindley().
For almost all other families, finite-difference approximations
to derivatives means that first and second derivatives can be
computed, even with models with 'xij' terms.
o Generic function wald.stat() implements Wald tests with SEs evaluated
at the null values, not at the original MLE, so do not suffer from the
Hauck-Donner effect.
o "vglm" objects have a new "charfun" slot, for the
characteristic function.
o "summary.vglm" and "summary.vlm" objects have new
"coef4lrt0", "coef4score0", "coef4wald0" slots, for
storing the 'Wald table' equivalent of LRTs, score tests and
modified Wald tests.
The latter has its SEs computed at the null values with the
other coefficients obtained by further IRLS iterations, etc.
Function summaryvglm() has arguments 'lrt0.arg', 'score0.arg',
'wald0.arg'.
o TIC() is new, for the Takeuchi's Information Criterion.
Thanks to Khedhaouiria Dikra for suggesting this.
o mills.ratio() and mills.ratio2() are exported.
o New functions: lrt.stat(), score.stat(), wald.stat(),
which.etas(), which.xij().
o cauchy1() and cauchy() handle multiple responses and have
been modernized a bit.
o Tested okay on R 3.4.3.
BUG FIXES and CHANGES
o Setting 'deriv.arg' a positive value in plotvgam() when there
are no s() terms results in a warning.
Thanks to Barry Goodwin for detecting this.
o cens.poisson() can better handle large lambda values, at least for
left and right censored data (but not for interval-censored data yet).
Thanks to Eugenie Hunsicker for picking up deficiencies in the code.
o In multinomial.Rd, it was stated that setting parallel = TRUE
did not make the intercepts the same. It does make them the same.
Thanks to Stuart Coles for picking this up.
o binomialff(multiple.responses = TRUE) returned an incorrect deviance.
o bilogistic() uses SFS rather than BFGS as its algorithm.
o Deprecated: lrp(), normal1() [use uninormal() instead].

math/R-VGAM: Import version 1.0-4 from pkgsrc-wip Vector generalized linear and additive models, and associated models (Reduced-Rank VGLMs, Quadratic RR-VGLMs, Reduced-Rank VGAMs). This package fits many models and distribution by maximum likelihood estimation (MLE) or penalized MLE. Also fits constrained ordination models in ecology. Packaged by Mike M. Volokhov, and updated by Kamil Rytarowski and me.
