It estimates the concentration and the ovalness parameter of some directional data assuming the Kent distribution. The mean direction and major and minor axes are also estimated.

`x` |
A matrix containing spherical data in Euclidean coordinates. |

The Kent distribution is fitted to some data and its parameters are estimated.

A list including:

`runtime` |
The run time of the procedure. |

`G` |
A 3 x 3 matrix whose first column is the mean direction. The second and third columns are the major and minor axes respectively. |

`para` |
The concentration |

`logcon` |
The logarithm of the normalising constant, using the third type apprxoimation. |

`loglik` |
The value of the log-likelihood. |
