pomp version 3.0.0.0 has been released: source code and binaries are available. This is a development release, anticipatory to the next CRAN version, which will be 3.1.
Important Changes
-
In
mif2
, the specification of particle numbers,Np
, has changed. WhenNp
is supplied as a function,Np(0)
is the requested number of particles at the beginning of the time series. The previous behavior was thatNp(1)
specified the requested number of particles. This behavior now matches that of the other particle filtering algorithms,pfilter
,bsmc2
, andpmcmc
. -
As promised from version 2.4.1, the
tol
andmax.fail
arguments have been removed completely from all particle-filtering algorithms, includingpfilter
,pmcmc
,bsmc2
, andmif2
. See the older post for more information. -
bsmc2
can now accept a variable number of particles, as do the other particle-filter based algorithmspfilter
,pmcmc
, andmif2
. -
The internal
systematic_resample
function now allows the user to specify the number of samples desired. Previously, these were always equal to the number of weights supplied. -
