pomp version 0.49-1 is now available on CRAN and coming soon to a mirror near you.
This is a new feature release. Some highlights are:
-
A new method,
probe.match.objfun
, constructs objective functions suitable for use in optimizers. -
Inference methods based on optimization can now use the
nloptr
package, which provides a suite of optimization algorithms. -
The new
abc
method implements Approximate Bayesian Computation for pomp models. -
New inline C functions
to_log_barycentric
andfrom_log_barycentric
are provided in pomp.h to facilitate log-barycentric transformations. These have proven very useful in dealing with parameters constrained to sum to one (e.g., initial conditions of compartmental models). -
Pomp objects now contain
dprior
andrprior
slots. These are used by the Bayesian methods (abc
,bsmc
, andpmcmc
). The oldhyperparams
argument to these methods has been removed; hyperparameters are now treated just as any others. -
By default,
pompBuilder
now creates all files in the temporary directory. Use thesave=TRUE
option to get the old behavior. -
The vignettes are no longer available via the
vignette()
command but can be reached via the HTML documentation, in thedoc
directory, and online at https://kingaa.github.io/pomp
