## Posterior probability of analogue-ness for fossil samples

### Description

Predict the posterior probability of analogue-ness between fossil and training set samples based on logistic regression fits.

### Usage

```
## S3 method for class 'logitreg'
predict(object, newdata, group = "all", k = 1, ...)
```

### Arguments

`object` |
an object of class |

`newdata` |
an object of class |

`group` |
character; for which group(s) are predictions
sought. |

`k` |
numeric; the number of close modern analogues to each fossil
sample to consider. Not currently used and may be removed from the
method as varying |

`...` |
additional arguments passed to other methods. |

### Value

A matrix of posterior probabilities of analogue-ness is returned. The
rows represent the fossil samples and the columns the groupings. There
are `g+1`

columns where `g`

is the number of groups. The
`g+1`

th column represents the Combined analysis which is the
overall posterior probability that a fossil sample is an analogue to a
training set sample (i.e. to any one of the groups).
