`ratings` |
n*2 matrix or dataframe, n subjects 2 raters. |

Missing data are omitted in a listwise way. The Bhapkar (1966) test is a more powerful alternative to the Stuart-Maxwell test. Both tests are asymptotically equivalent and will produce comparable chi-squared values when applied a large sample of rated objects.

A list with class "irrlist" containing the following components:

`$method` |
a character string describing the method. |

`$subjects` |
the number of data objects. |

`$raters` |
the number of raters. |

`$irr.name` |
the name of the coefficient (Chisq). |

`$value` |
the value of the coefficient. |

`$stat.name` |
the name and df of the test statistic. |

`$statistic` |
the value of the test statistic. |

`$p.value` |
the probability of the test statistic. |
