getIid {BuyseTest} | R Documentation |

## Extract the H-decomposition of the Estimator

### Description

Extract the H-decomposition of the GPC estimator.

### Usage

```
getIid(
object,
endpoint = NULL,
statistic = NULL,
strata = FALSE,
cumulative = TRUE,
center = TRUE,
scale = TRUE,
type = "all",
cluster = NULL,
simplify = FALSE
)
## S4 method for signature 'S4BuyseTest'
getIid(
object,
endpoint = NULL,
statistic = NULL,
strata = FALSE,
cumulative = TRUE,
center = TRUE,
scale = TRUE,
type = "all",
cluster = NULL,
simplify = TRUE
)
```

### Arguments

`object` |
an |

`endpoint` |
[character] for which endpoint(s) the H-decomposition should be output?
If |

`statistic` |
[character] statistic relative to which the H-decomposition should be output. |

`strata` |
[character vector] the strata relative to which the H-decomposition of the statistic should be output.
Can also be |

`cumulative` |
[logical] should the H-decomposition be cumulated over endpoints? Otherwise display the contribution of each endpoint. |

`center` |
[logical] if |

`scale` |
[logical] if |

`type` |
[character] type of H-decomposition to be output.
Can be only for the nuisance parameters ( |

`cluster` |
[numeric vector] return the H-decomposition aggregated by cluster. |

`simplify` |
[logical] should the result be coerced to the lowest possible dimension? |

### Details

WARNING: argument `scale`

and `center`

should be used with care as when set to `FALSE`

they may not lead to a meaningful decomposition.

### Value

A list of matrices, each element of the list correspond to a statistic (global or strata-specific) and each matrix has as many columns as endpoints and rows as observations.
