skeleton {pomp} | R Documentation |
skeleton workhorse
Description
Evaluates the deterministic skeleton at a point or points in state space, given parameters.
In the case of a discrete-time system, the skeleton is a map.
In the case of a continuous-time system, the skeleton is a vectorfield.
NB: skeleton
just evaluates the deterministic skeleton;
it does not iterate or integrate (see flow
and trajectory
for this).
Usage
## S4 method for signature 'pomp'
skeleton(
object,
x = states(object),
times = time(object),
params = coef(object),
...
)
Arguments
object |
an object of class ‘pomp’, or of a class that extends ‘pomp’.
This will typically be the output of |
x |
an array containing states of the unobserved process.
The dimensions of |
times |
a numeric vector (length |
params |
a |
... |
additional arguments are ignored. |
Value
skeleton
returns an array of dimensions nvar
x nrep
x ntimes
.
If f
is the returned matrix, f[i,j,k]
is the i-th component of the deterministic skeleton at time times[k]
given the state x[,j,k]
and parameters params[,j]
.
