R: Estimate number of record pairs.

getExpectedSize {RecordLinkage} | R Documentation

## Estimate number of record pairs.

### Description

Estimates the total number of record pairs generated by a dataset and specified blocking conditions.

### Usage

      getExpectedSize(object, ...)

      ## S4 method for signature 'RLBigDataDedup'
    getExpectedSize(object)

      ## S4 method for signature 'RLBigDataLinkage'
    getExpectedSize(object)

      ## S4 method for signature 'data.frame'
    getExpectedSize(object, blockfld = list())

### Arguments

`object` | Either a record linkage object or a dataset.
`blockfld` | A blocking definition, such as in `compare.dedup`
`...` | Placeholder for additional arguments.

### Details

The `"RLBigData*"` methods are only left for backward compatibility. Since version 0.4, all record pairs for such objects are generated and stored in a disk file. The methods return the true number of record pairs.

For the `"data.frame"` method, estimation is based on the assumption that agreement or disagreement of one attribute is independent of the other attributes.

`blockfld` is a blocking definition such as for `RLBigDataDedup`.

### Value

The expected number of record pairs.
