## Calculates the excess masses associated with the
nodes of a level set tree

### Description

Given a level set tree,
calculates the excess mass for every node of the tree.
The excess mass is the probability mass under the curve,
over a given level,
in a certain branch of the level set tree.
For example, function "leafsfirst" returns a level set tree.

### Usage

excmas(lst)

### Arguments

`lst` |
level set tree object;
list of vectors which is the output of for example
"leafsfirst", "profkern", "profhist", or "profgene" |

### Value

Vector whose length is equal to the number of nodes of the level set tree.
