Performs test for the composite hypothesis of exponentiality based on the Pietra statistic, see e.g. Ascher (1990).

1 | ```
pietra.exp.test(x, nrepl=2000)
``` |

`x` |
a numeric vector of data values. |

`nrepl` |
the number of replications in Monte Carlo simulation. |

The test is based on the Pietra statistic

*
P_n =∑_{i=1}^n\frac{|X_i-\overline{X}|}{2n\overline{X}}.
*

The p-value is computed by Monte Carlo simulation.

A list with class "htest" containing the following components:

`statistic` |
the value of the Pietra statistic. |

`p.value ` |
the p-value for the test. |

`method` |
the character string "Test for exponentiality based on the Pietra statistic". |

`data.name` |
a character string giving the name(s) of the data. |
