pomp version 0.53-1 is now available on CRAN and coming soon to a mirror near you.
This is a major new feature release. Some highlights are:
- It is now much easier to accelerate code through the use of compiled code.
pomp can now take snippets of C code directly as definitions of the various basic functions. This is accomplished through the use of a new Csnippet function. See the “sir” demo for a demonstration.
-
Features that facilitate multiple PMCMC and ABC chains have been added. There are
c
methods to combineabc
andpmcmc
objects. Runningconv.rec
on anabc
,pmcmc
,abcList
, orpmcmcList
object now produces codamcmc
andmcmc.list
objects, respectively. Diagnostic plots are produced by runningplot
on such objects. Package coda is now a dependency of pomp. This package provides various generic MCMC diagnostics. -
The
transform
argument forpmcmc
andabc
has been removed. -
nlf
now returns an S4 object of classnlfd.pomp
with alogLik
method for extracting the log quasi likelihood and a$
method for extracting arbitrary components.
It thus behaves like pomp's other inference methods. -
The package manual and tutorials are no longer included with the package source. Instead, links are provided to the pomp website. The package help pages have been revisited for accuracy and completeness.
