Negative log likelihood of the generalized Pareto distribution (expected shortfall)
Negative log likelihood of the generalized Pareto distribution (expected shortfall) - optimization The negative log likelihood is parametrized in terms of log expected shortfall and shape in order to perform unconstrained optimization
Arguments
- par
vector of length 2 containing \(e_m\) and \(\xi\), respectively the expected shortfall at probability 1/(1-\(\alpha\)) and the shape parameter.
- dat
sample vector
- m
number of observations of interest for return levels. See Details
