Arguments
- Data

Value
Plot of the empirical mean excess function (black line), average of all observations exceeding a threshold decreased by the threshold, for thresholds spanning the range of the observations. Also provided are 95% confidence intervals (blue dotted lines) and the observations (black dots).
