numeric vector of data, which may have a times
attribute containing (in an object of class "POSIXct", or
an object that can be converted to that class; see
as.POSIXct) the times/dates of each observation.
If no times attribute exists, the data are assumed to
be equally spaced.
threshold
a threshold value (either this or nextremes
must be given but not both)
nextremes
the number of upper extremes to be used (either
this or threshold must be given but not both)
run
if the data are to be declustered the run length
parameter for the runs method (see decluster)
should be entered here
picture
whether or not a picture should be drawn if
declustering is performed

arguments passed to optim
Value
An object of class "potd" describing the fit and including
parameter estimates and standard errors.
Details
Uses optim for point process likelihood maximization.
