predictive_pdf | R Documentation |

`predictive_pdf()`

evaluates the predictive PDF of the model specified
by a `DataDistribution`

`dist`

and
`Prior`

at the given stage-one outcome.

```
predictive_pdf(dist, prior, x1, n1, ...)
## S4 method for signature 'DataDistribution,ContinuousPrior,numeric'
predictive_pdf(
dist,
prior,
x1,
n1,
k = 10 * (prior@support[2] - prior@support[1]) + 1,
...
)
## S4 method for signature 'DataDistribution,PointMassPrior,numeric'
predictive_pdf(dist, prior, x1, n1, ...)
```

`dist` |
a univariate |

`prior` |
a |

`x1` |
stage-one test statistic |

`n1` |
stage-one sample size |

`...` |
further optional arguments |

`k` |
number of pivots for crude integral approximation |

`numeric`

, value of the predictive PDF

```
tmp <- ContinuousPrior(function(x) dunif(x, .2, .4), c(.2, .4))
predictive_pdf(Normal(), tmp, 2, 20)
predictive_pdf(Normal(), PointMassPrior(.3, 1), 1.5, 20) # ~.343
```
