mif-class {pomp} | R Documentation |
The mif
class holds a fitted model and is created by a call to mif
.
See mif
for usage.
Objects can be created by calls to the mif
method on an pomp
object.
Such a call uses the MIF algorithm to fit the model parameters.
A mif
object is derived from a pomp
object and therefore has all the slots of such an object.
See pomp-class
for details.
A full description of slots in a mif
object follows.
particles(Np,center,sd,...)
that draws particles from a distribution centered on center
and with width proportional to sd
.
This function can be optionally specified by the user.
Np
, the number of particles to use in filtering;
var.factor
, the scaling coefficient relating the width of the initial particle distribution to rw.sd
;
ic.lag
, the fixed lag used in the estimation of initial-value parameters (IVPs);
and cooling.factor
, the exponential cooling factor, where 0<cooling.factor<1
