CHANGES

```
0.2 first version to CRAN
0.2-1 fixed bugs in docs found by scripts on CRAN (R-devel check)
0.3 added data/echinacea.txt
man/echinacea.Rd
test/tutor.R
added test in aster.R
added package vignette
added examples on all help pages to be used by users
0.3-1 changed variable "site" to "pop" in echinacea.txt
corresponding changes in many other files
\usepackage[utf8]{inputenc} in tutor.Rnw
many small changes in wording in tutor.Rnw
0.4 made trust the default optimizer
0.4-1 removed the timing.pdf vignette, fixed xrefs to trust in Rd files
0.4-2 added import(trust) to NAMESPACE
0.5 added 4-th family "two.trunc.poisson"
actually implemented code for k-truncated Poisson
put document describing k-truncated Poisson in inst/doc
new R function rktp that simulates k-truncated Poisson
cannot implement k-truncated Poisson for arbitrary family
until families get (non-exponential family) parameters,
such as k for k-truncated Poisson, r for negative binomial,
offset for Poisson, n for binomial(n, p), sigma for
normal-location. All of that goes on the to-do list,
along with multivariate families (as per revised version of
the paper), especially multinomial and normal-location-scale.
fixed (?!) or at least worked around nasty validation bug in
predict.aster
0.5-1 fixed bug in tests/tutor.R caused by bug fix in R. optim was ignoring
its maxit argument when method == "CG". When it stopped ignoring
it, it failed to converge, because it takes more than 1000
iterations.
0.5-2 fixed bug in inst/doc/trunc.Rnw -- must be vignette to pass R CMD check
0.6 new superfamily system: exponential families with non-exponential
family hyperparameters
canonical affine models
0.6-1 negative binomial distribution
0.6-2 truncated negative binomial distribution
fixed bug in 0.6 and 0.6-1 that made them useless with models
that did not have unrestricted canonical parameter space:
mlogl could return NaN rather than Inf (which is what it
is supposed to do) when evaluating at point outside the
canonical space. Now hopefully fixed with new code
in astunco.c and astcond.c. (TODO: need more tests with
restricted parameter space. foobar.R is not enough. Note
0.6 and 0.6-1 were not made public, so no one bug CJG saw
this bug. Still it does show the tests directory is deficient.)
0.7 added normal-location families; see ?fam.normal.location
0.7-1 fixed incorrect signature in as.character.astfam
0.7-2 new data sets: echin2 chamae2 chamae aphid
added warning (varb must be factor) to vignette
0.7-3 unmatched braces in .Rd files chamae2 chamae
0.7-4 fixed bug in predict.aster.formula documentation.
amat is three-way array just as for predict.aster
example already required this.
removed tests/tutor.R took too long and tested nothing specific
0.7-5 added newcoef argument to predict.aster and predict.aster.formula
0.7-6 fix doc bug found by Rd version 2 parser
0.7-7 add sim.rda dataset for TR 669 and 674 Also add references to aster.Rd
