object |
an object of class extending ‘pomp’, the result of the application of a parameter estimation algorithm |
pars |
names of parameters |
transform |
logical; should the traces be transformed back onto the natural scale? |
... |
ignored or (in the case of the listie, passed to the more primitive function) |
Note that pmcmc
does not currently support parameter transformations.
When object
is the result of a mif2
calculation,
traces(object, pars, transform = FALSE)
returns the traces of the parameters named in pars
.
By default, the traces of all parameters are returned.
Note that, if the computation was performed with transformed parameters, the traces are on the estimation scale.
If transform=TRUE
, the parameters are transformed from the estimation scale onto the natural scale.
When object
is a ‘abcd_pomp’, traces(object)
extracts the traces as a coda::mcmc
.
When object
is a ‘abcList’, traces(object)
extracts the traces as a coda::mcmc.list
.
When object
is a ‘pmcmcd_pomp’, traces(object)
extracts the traces as a coda::mcmc
.
When object
is a ‘pmcmcList’, traces(object)
extracts the traces as a coda::mcmc.list
.
