A fitted point process model of class
Character vector specifying which quantities are to be calculated. Default is to calculate all quantities.
Components of the score vector and Hessian matrix for the irregular parameters, if required. See Details.
List of extra arguments for the functions
Logical. Whether to include (
Optional character string name for the fitted model
This function calculates all the
leverage and influence measures
When analysing large datasets, the user can
ppmInfluence to perform the calculations efficiently,
then extract the leverage and influence values as desired.
For example the leverage can be extracted either as
If the point process model trend has irregular parameters that were
then the influence calculation requires the first and second
derivatives of the log trend with respect to the irregular parameters.
iScore should be a list,
with one entry for each irregular parameter, of R functions that compute the
partial derivatives of the log trend (i.e. log intensity or
log conditional intensity) with respect to each irregular
parameter. The argument
iHessian should be a list,
with p^2 entries where p is the number of irregular
parameters, of R functions that compute the second order
partial derivatives of the
log trend with respect to each pair of irregular parameters.
A list containing the leverage and influence measures specified by
what. The result also belongs to the class
