(`Ln`

)`SplitMatchProbability()`

calculates the probability that two random
splits of the sizes provided will be at least as similar as the two
specified.

```
SplitMatchProbability(split1, split2)
LnSplitMatchProbability(split1, split2)
```

## Arguments

- split1, split2
Logical vectors listing terminals in same order, such that
each terminal is identified as a member of the ingroup (`TRUE`

) or outgroup
(`FALSE`

) of the respective bipartition split.

## Value

`SplitMatchProbability()`

returns a numeric giving the proportion
of permissible non-trivial splits that divide the terminals into bipartitions
of the sizes given, that match as well as `split1`

and `split2`

do.

`LnSplitMatchProbability()`

returns the natural logarithm of the
probability.

## Examples

```
split1 <- as.Splits(c(rep(TRUE, 4), rep(FALSE, 4)))
split2 <- as.Splits(c(rep(TRUE, 3), rep(FALSE, 5)))
SplitMatchProbability(split1, split2)
#> [1] 0.1428571
LnSplitMatchProbability(split1, split2)
#> [1] -1.94591
