Multivariate kernel density estimation.

1 | ```
mkde(x, h, thumb = "none")
``` |

`x` |
A matrix with Euclidean (continuous) data. |

`h` |
The bandwidh value. It can be a single value, which is turned into a vector and then into a diagonal matrix, or a vector which is turned into a diagonal matrix. |

`thumb` |
Do you want to use a rule of thumb for the bandwidth parameter? If no, leave it "none", or else put "estim" for maximum likelihood cross-validation, "scott" or "silverman" for Scott's and Silverman's rules of thumb respectively. |

The multivariate kernel density estimate is calculated with a (not necssarily given) bandwidth value. It is used a wrapper for the function `comp.kerncontour`

.

A vector with the density estimates calculated for every vector.
