Estimates idealised priorities of alternatives (the rating AHP model).

1 | ```
rating(scale, alternative, NA_category = NULL, simulation = 500)
``` |

`scale` |
a pairwise comparison matrix (PCM) of rating categories. |

`alternative` |
a N by 2 character matrix, where N is the number of alternatives. The matrix includes alternatives on column #1 and the rating category they belong to on column #2. |

`NA_category` |
a character string or vector which specifies categories with the value of zero. Since zero is not achievable by PCM matrix. |

`simulation` |
simulation size for computation of Saaty's inconsistency |

An S4 object including the raw and normalized ahp priorities, Satty's inconsistency, and rating matrix.
