Given a vector of exceedances and some potential choices of \(k\) for the threshold, compute the left-truncated Hill estimators for each value of k and use these to compute the variance and slope of the estimator
Usage
tstab.lthill(xdat, k, which = c("lthill", "var", "slope"), log = TRUE, ...)Arguments
- xdat
- [numeric] vector of positive observations 
- k
- [integer] number of order statistics for the threshold 
- which
- [string] the type of plot, showing the left-truncated Hill plot on the log, the log of the variance of the estimator, or the log slope 
- log
- [logical] if - TRUE(default), shows the Hill plot on the log-scale
- ...
- additional parameters for color, etc. to be passed to plot
