| profile2d.evd {evd} | R Documentation |
Calculate joint profile traces for fitted models.
## S3 method for class 'evd':
profile2d(fitted, prof, which, pts = 20, convergence =
FALSE, method = "Nelder-Mead", control = list(maxit = 5000), ...)
fitted |
An object of class "evd". |
prof |
An object of class "profile.evd", created using
profile.evd with argument fitted.
The object must contain the (marginal) profile traces for the two
parameters specified in which. |
which |
A character vector of length two containing the original model parameters that are to be jointly profiled. |
pts |
The number of distinct values used for each profiled
parameter in which.
There are pts^2 optimizations performed in total. |
convergence |
Logical; print convergence code after each
optimization? (A warning is given for each non-zero convergence
code, irrespective of the value of convergence.) |
method |
The optimization method. |
control |
Passed to optim. See optim for
details. |
... |
Ignored. |
An object of class "profile2d.evd", which is a list with three
elements.
The first element, a matrix named trace, has the same structure
as the elements of an object of class "profile.evd".
The last two elements give the distinct values used for each profiled
parameter in which.
