|
data |
either a data frame holding the time series data, or an object of class ‘pomp’, i.e., the output of another pomp calculation. |
Np |
the number of particles to use. |
h |
function returning the expected value of the observation given the state. |
R |
matrix; variance of the measurement noise. |
params |
optional; named numeric vector of parameters.
This will be coerced internally to storage mode |
rinit |
simulator of the initial-state distribution.
This can be furnished either as a C snippet, an R function, or the name of a pre-compiled native routine available in a dynamically loaded library.
Setting |
rprocess |
simulator of the latent state process, specified using one of the rprocess plugins.
Setting |
... |
additional arguments supply new or modify existing model characteristics or components.
See When named arguments not recognized by |
verbose |
logical; if |
C |
matrix converting state vector into expected value of the observation. |
An object of class ‘kalmand_pomp’.
