pomp (version 0.21-3)

skeleton-pomp: Evaluate the deterministic skeleton at the given points in state space.

Description

The method skeleton computes the deterministic skeleton. In the case of a discrete-time system, this is the one-step map. In the case of a continuous-time system, this is the vector-field. NB: skeleton just evaluates the deterministic skeleton; it does not iterate or integrate.

Usage

skeleton(object, x, t, params, ...)
## S3 method for class 'pomp':
skeleton(object, x, t, params, \dots)

Arguments

object

an object of class pomp.

x

a rank-3 array containing the states of the unobserved process at which the deterministic skeleton is to be evaluated. The dimensions of x are nvars x nreps x ntimes, where nvars is the

t

a numeric vector containing the times at which the deterministic skeleton is to be evaluated.

params

a rank-2 array of parameters with columns corresponding to the columns of x. Note that the x and params must agree in the number of their columns.

...

at present, these are ignored.

Value

• Returns an array of dimensions nvar x nreps 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].

Details

This function makes repeated calls to the user-supplied skeleton of the pomp object. For specifications on supplying this, see pomp.
