Description Usage Format Details References Examples

This dependence structure is constructed by applying the function :

h(u_1,u_2,u_3) = (u_{1},\sin(2π u_{1})-\frac{u_{2}}{π},(1+\frac{u_{3}}{π^{2}})(\frac{u_{3}}{2} I_{\frac{1}{4}≥ u_1}-\sin(π^{x_{1}}) I_{\frac{1}{4} < u_{1}}))

to uniformly drawn 3-dimensional random vectors. The dataset is the ranks of h(u).

1	funcdep_data

A matrix with 500 rows and 3 columns

The example section below gives the code to re-generate this data if needed.

This dataset is studied in O. Laverny, V. Maume-Deschamps, E. Masiello and D. Rullière (2020).
