Implements a variety of functions to approximate expected ranks for partial rankings.

1 | ```
approx_rank_expected(P, method = "lpom")
``` |

`P` |
A partial ranking as matrix object calculated with neighborhood_inclusion or positional_dominance. |

`method` |
String indicating which method to be used. see Details. |

The *method* parameter can be set to

- lpom
local partial order model

- glpom
extension of the local partial order model.

- loof1
based on a connection with relative rank probabilities.

- loof2
extension of the previous method.

Which of the above methods performs best depends on the structure and size of the partial
ranking. See `vignette("benchmarks",package="netrankr")`

for more details.

A vector containing approximated expected ranks.
