profliker | R Documentation |
Find the profile likelihood for a range of values for an extreme value df (EVD).
profliker(object, type = c("return.level", "parameter"), xrange = NULL,
return.period = 100, which.par = 1, nint = 20, plot = TRUE, gr = NULL,
method = "BFGS", lower = -Inf, upper = Inf, control = list(), ...)
object |
A list object of class “fevd” as returned by |
type |
character string stating whether the parameter of interest is a regular parameter or a return level. |
xrange |
numeric vector of length two giving the range of values of the parameter over which to calculate the profile likelihood. |
return.period |
If a return level is of interest, this number gives its associated return period. |
which.par |
If a parameter is of interest, this number tells for which component of the parameter vector to do the profile likelihood. |
nint |
The profile likelihood is calculated for a sequence of |
plot |
logical; should a plot of the likelihood be made? Note that this is controlled by the |
gr , method , lower , upper , control |
optional arguments to |

A numeric vector is returned invisibly.
