The `likestim`

function gives multiloci estimation of the number of contributors to a forensic DNA mixture
using likelihood maximization.

`mix` |

`freq` |
a |

`refpop` |
the reference population from which to extract the allele frequencies used in the likelihood
calculation. If |

`theta` |
a float from [0,1[ giving Wright's Fst coefficient. |

`loc` |
loci to be considered in the estimation. Default (set to NULL) corresponds to all loci. |

The number of contributors which maximizes the likelihood of the data observed in the mixture is searched in the discrete interval [1,6]. In most cases this interval is a plausible range for the number of contributors.

A matrix of dimension 1 x 2, the first column, `max`

, gives the maximum likelihood estimation of the number of contributors,
the second column
gives the corresponding likelihood value `maxvalue`

.
