test-edges | R Documentation |

Test edges in graphical models with p-value/AIC
value. The models must be `iModel`

s.

```
testEdges(
object,
edgeMAT = NULL,
ingraph = TRUE,
criterion = "aic",
k = 2,
alpha = NULL,
headlong = FALSE,
details = 1,
...
)
testInEdges(
object,
edgeMAT = NULL,
criterion = "aic",
k = 2,
alpha = NULL,
headlong = FALSE,
details = 1,
...
)
testOutEdges(
object,
edgeMAT = NULL,
criterion = "aic",
k = 2,
alpha = NULL,
headlong = FALSE,
details = 1,
...
)
```

`object` |
An |

`edgeMAT` |
A |

`ingraph` |
If TRUE, edges in graph are tested; if FALSE, edges not in graph are tested. |

`criterion` |
Either |

`k` |
Penalty term when |

`alpha` |
Critical value for deeming an edge to be significant/
insignificant. When |

`headlong` |
If TRUE then testing will stop once a model improvement has been found. |

`details` |
Controls the level of printing on the screen. |

`...` |
Further arguments to be passed on to |

testIn: Function which tests whether each edge in "edgeList" can be delete from model "object"

testOut: Is similar but in the other direction.

A dataframe with test statistics (p-value or change in AIC), edges and logical telling if the edge can be deleted.

cm1 <- cmod(~me:ve + ve:al + al:an, data=math)
testEdges(cm1, ingraph=TRUE)
