pomp-class {pomp} | R Documentation |
The class pomp
encodes a partially-observed Markov process.
Objects should be created by calls of the function
pomp
. See the documentation for pomp
for
usage instructions and important warnings.
nobs
x ntimes
, where nobs
is the number of
observed variables and ntimes
is the number of times at which
observations were made.times
must be a strictly increasing numeric vector.rprocess(xstart,times,params,...)
which simulates from the
unobserved process.dprocess(x,times,params,log=FALSE,...)
which evaluates
the likelihood of a sequence of consecutive state transitions.rmeasure(x,times,params,...)
which simulates from the observation process.dmeasure(y,x,params,log=FALSE,...)
which gives the
likelihood of y
given x
.pomp
object in a nice way.pomp
object.data.array(object)
returns the array of
observations. data.array(object,vars)
gives just the
observations of variables vars
. vars
may specify
the variables by position or by name.pomp
object can be coerced to a data-frame
via as(object,"data.frame")
.rprocess-pomp
.dprocess-pomp
.rmeasure-pomp
.dmeasure-pomp
.simulate
can be used to simulate state and/or
observation trajectories. See documentation under
simulate-pomp
