effect: Consider the effect of particular places upon the ID

Description Usage Arguments Details Value See Also Examples

View source: R/effect.R

Description

Evaluates the effect on the index of the named places under three different scenarios.

Usage

1
effect(object, places)

Arguments

object

an object of class index: a multilevel index created using function id

places

a character vector containing the names of the places in any of the higher-level geographies for which the evaluation will be made

Details

The three different scenarios considered are:

  1. if the effects (the estimated residuals from the multilevel model) are set to zero for the named higher-level places;

  2. if the shares of the two population groups are equal everywhere except within the named places; and

  3. if all but the neighbourhoods within the named places are omitted from the data and the index then recalculated using only those that remain.

The evaluation also includes:

See vignette("MLID") for further details

Value

an object, primarily a list containing the evaluated values
