Performs parameter transformations.
# S4 method for pomp
partrans(object, params, dir = c("fromEst", "toEst"),
...)
an object of class ‘pomp’, or of a class that extends ‘pomp’.
This will typically be the output of pomp
, simulate
, or one of the pomp inference algorithms.
a npar
x nrep
matrix of parameters.
Each column is treated as an independent parameter set, in correspondence with the corresponding column of x
.
the direction of the transformation to perform.
additional arguments are ignored.
If dir=fromEst
, the parameters in params
are assumed to be on the estimation scale and are transformed onto the natural scale.
If dir=toEst
, they are transformed onto the estimation scale.
In both cases, the parameters are returned as a named numeric vector or an array with rownames, as appropriate.
