particles(object, ...) ## S4 method for signature 'mif': particles(object, Np = 1, center = coef(object), sd = 0, ...)
object |
the "mif" object |
Np |
the number of particles, i.e., number of draws. |
center |
the central value of the distribution of particles |
sd |
the width of the distribution |
... |
additional arguments. At present, these are ignored. |
The particles
method is used to set up the initial distribution
of particles. It is an interface to the user-specifed
particles
slot in the "mif" object.
particles
returns a list of two matrices. states
contains the state-variable portion of the particles; params
contains the parameter portion. Each has Np
