## Measures of health inequality included in `healthequal`

:

The following summary measures of health inequality are included in the `healthequal`

package:

### Simple measures

### Disproportionality measures (ordered dimensions)

- Absolute concentration index (
`aci`

)
- Relative concentration index (
`rci`

)

### Regression-based measures (ordered dimensions)

- Slope index of inequality (
`sii`

)
- Relative index of inequality (
`rii`

)

### Variance measures (non-ordered dimensions)

- Between-group variance (
`bgv`

)
- Between-group standard deviation (
`bgsd`

)
- Coefficient of variation (
`covar`

)

### Mean difference measures (non-ordered dimensions)

- Mean difference from mean - unweighted and weighted (
`mdmu`

and `mdmw`

)
- Mean difference from best-performing subgroup - unweighted and weighted (
`mdbu`

and `mdbw`

)
- Mean difference from reference subgroup - unweighted and weighted (
`mdru`

and `mdrw`

)
- Index of disparity - unweighted and weighted (
`idisu`

and `idisw`

)

### Disproportionality measures (non-ordered dimensions)

- Theil index (
`ti`

)
- Mean log deviation (
`mld`

)

### Impact measures

- Population attributable risk (
`parisk`

)
- Population attributable fraction (
`paf`

)

# Package data

The `healthequal`

package comes with sample data for users to be able to test the package functions. The `OrderedSample`

and `NonorderedSample`

data contain data disaggregated by economic status and subnational region, respectively, for a single indicator.

### Ordered and Nonordered data

### Disagregated data

The `OrderedSampleMultipleind`

and `OrderedSampleMultipleind`

data contain disaggregated data by economic status and subnational region, respectively, for two indicators.
