particles(object, ...)
## S4 method for signature 'mif'
particles(object, Np = 1, center = coef(object), sd = 0, ...)

Arguments

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.

Details

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.

Value

particles returns a list of two matrices. states contains the state-variable portion of the particles; params contains the parameter portion. Each has Np columns.
