## Tri-variate ‘angular’ data set approximately distributed according to a multivariate extremes angular distribution

### Description

The data set is constructed from coordinates (columns) *1,2,3* of `frechetdat`

.
It contains 100 angular points corresponding to the tri-variate vectors *V=(X,Y,Z)* with largest *L1* norm (*||V||=X+Y+Z*). The angular points are obtained by ‘normalizing’: *e.g.*,
*x=X/||V||*. Thus,
each row in `Leeds`

is a point on the two-dimensional simplex : *x+y+z=1*.

### Format

A *100*3* - matrix.
