ExcessMass (version 1.0.1)

ExcessMass: Excess Mass Calculation and Plots

Description

Implementation of a function which calculates the empirical excess mass for a given \(\lambda\) and given maximal number of modes (excessm). Offering powerful plot features to visualize empirical excess mass (exmsilhouette). This includes the possibility of drawing several plots (with different maximal number of modes / cut off values) in a single graph. Furthermore, plotting the empirical excess mass against lambda is implemented (exmplot).
