# estimate Abundances from sonicated samples

### Description

When one or more replicate samples are sonicated and the lengths for each integration site are recorded, it is of interest to estimate actual number of sonicants allowing for coincidentally equal lengths. A likelihood approach is used here.

### Usage

1 |

### Arguments

`locations` |
a vector of IDs for distinct locations |

`lengths` |
a vector of the corresponding lengths |

`replicates` |
an optional vector of the replicate sample ID |

`jackknife` |
Whether to do leave-one-out jackknife samples over the replicates |

`kmax` |
highest count to bother with when computing mass function
for counts. All higher values are
globbed together in the result. If |

`...` |
Other arguments that may be passed along to functions that do the real work. |

### Details

This is a wrapper function for `maxEM`

so study that
function to see what is going on.

### Value

a list with components

`theta` |
estimated abundances |

`phi` |
estimated bin probabilities |

`var.theta` |
variances of |

`iter` |
number of iterations till convergence was achieved |

`call` |
the function call |

`lframe` |
the |

`obs` |
the observed counts of distinct lengths |

`jackknife` |
a list of calls to |

`data` |
a |
