fit_nhpp | R Documentation |
Fit a non-homogeneous Poisson process model to the exceedances of a time series.
fit_nhpp(x, tau, ...)
x |
A time series |
tau |
A vector of changepoints |
... |
currently ignored |
Any time series can be modeled as a non-homogeneous Poisson process of the
locations of the exceedances of a threshold in the series.
This function uses the BMDL criteria to determine the best fit
parameters for each
region defined by the changepoint set tau
.
An nhpp
object, which inherits from mod_cpt.
