Defunct: use `indep.test`

with `method = mvI`

.
Computes a multivariate nonparametric E-statistic and test of independence.

1 2 | ```
indep.e(x, y)
indep.etest(x, y, R)
``` |

`x` |
matrix: first sample, observations in rows |

`y` |
matrix: second sample, observations in rows |

`R` |
number of replicates |

Computes the coefficient *I_n* and performs a nonparametric
*E*-test of independence. The test decision is obtained via
bootstrap, with `R`

replicates.
The sample sizes (number of rows) of the two samples must agree, and
samples must not contain missing values. The statistic
*E = I^2* is a ratio of V-statistics based
on interpoint distances *||x_{i}-y_{j}||*.
See the reference below for details.

The sample coefficient *I* is returned by `indep.e`

.
The function `indep.etest`

returns a list with class
`htest`

containing

`statistic` |
observed value of the coefficient |

`p.value` |
approximate p-value of the test |

`data.name` |
