The null hypothesis is whether a von Mises-Fisher distribution fits the data well, where the altenrative is that Kent distribution is more suitable.

1 | ```
fishkent(x, B = 999)
``` |

`x` |
A numeric matrix containing the data as unit vectors in Euclidean coordinates. |

`B` |
The number of bootstrap re-samples. By default is set to 999. If it is equal to 1, no bootstrap is performed and the p-value is obtained throught the asymptotic distribution. |

Essentially it is a test of rotational symmetry, whether Kent's ovalness parameter (beta) is equal to zero. This works for spherical data only.

A vector including:

`test` |
The value of the test statistic |

`p-value or Bootstrap p-value` |
The p-value of the test. |
