Likelihood Ratio statistic for the exponential distribution vs. GPD.
LRExp(x, alternative = c("lomax", "GPD", "gpd", "maxlo"))
The LR statistic value.
Numeric vector of positive sample values. For the POT context, this should be the vector of excesses over the threshold.
Character string describing the alternative hypothesis
The Likelihood-Ratio statistic is actually \(W:=-2 \log \textrm{LR}\) where LR is the ratio of the likelihoods exponential to alternative distribution.
