Tests for multivariate location using different score functions.

1 2 3 | ```
mv.1sample.test(X, mu = 0, score = "identity", stand = "outer",
method = "approximation", n.simu = 1000,
na.action = na.fail)
``` |

`X` |
a numeric data frame or matrix. |

`mu` |
the null hypothesis value. Default is the zero vector. |

`score` |
the score to be used. Possible choices are |

`stand` |
the standardization method used. Possible choices are |

`method` |
method for the computation of the p-value for the spatial sign and spatial signed-rank tests.
Possible choices are |

`n.simu` |
number of simulated sign changes if |

`na.action` |
a function which indicates what should happen when the data contain 'NA's. Default is to fail. |

The tests provided here are the Hotelling's T^2 test, the spatial sign test and the signed-rank test and their affine invariant versions in the one sample location case.

Note that for the identity score the provided test is not the traditional Hotelling's T^2 test because here the covariance matrix is computed wrt to the null value and not wrt to the sample mean.
Use the function `HotellingsT2`

for the traditional version of Hotelling's T^2 test.
Details about the tests can be found in the chapters 5-8 of the MNM book.

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

`statistic ` |
the value of the test statistic. |

`parameter` |
the degrees of freedom for the test statistic or the number of replications in the simulation. |

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

`null.value` |
the specified hypothesized value of the location. |

`alternative` |
a character string with the value 'two.sided'. |

`method` |
a character string indicating what type of test was performed. |

`data.name` |
a character string giving the name of the data set. |
