`R/RcppExports.R`

`posterior.Rd`

Calculate posterior for one item given score, difficulty and prior

posterior(score, tau, prior, qp)

score | Integer, either 0 (fail) and 1 (pass) |
---|---|

tau | Numeric, difficulty parameter |

prior | Vector of prior values on quadrature points |

qp | vector of equally spaced quadrature points |

A vector of length `length(prior)`

This function assumes that the difficulties have been estimated by
a binary Rasch model (e.g. by
`sirt::rasch.pairwise.itemcluster()`

).
