Estimates the at-risk-of-poverty threshold (defined as percentage (usually 60%) of equalised disposable income after social transfers quantile (usually median)) and computes linearized variable for variance estimation.

Y |
Study variable (for example equalised disposable income after social transfers). One dimensional object convertible to one-column |
id |
Optional variable for unit ID codes. One dimensional object convertible to one-column |
weight |
Optional weight variable. One dimensional object convertible to one-column |
sort |
Optional variable to be used as tie-breaker for sorting. One dimensional object convertible to one-column |
Dom |
Optional variables used to define population domains. If supplied, linearization of at-risk-of-poverty threshold is done for each domain. An object convertible to |
period |
Optional variable for survey period. If supplied, linearization of at-risk-of-poverty threshold is done for each survey period. Object convertible to |
dataset |
Optional survey data object convertible to |
percentage |
A numeric value in range [0,100] for p in the formula for at-risk-of-poverty threshold computation: p/100 * Z(α/100). For example, to compute poverty threshold equal to 60% of some income quantile, p should be set equal to 60. |
order_quant |
A numeric value in range [0,100] for α in the formula for at-risk-of-poverty threshold computation: p/100 * Z(α/100). For example, to compute poverty threshold equal to some percentage of median income, α should be set equal to 50. |
var_name |
A character specifying the name of the linearized variable. |
checking |
Optional variable if this variable is TRUE, then function checks data preparation errors, otherwise not checked. This variable by default is TRUE. |
The implementation strictly follows the Eurostat definition.
A list with three objects are returned:
quantile
- a data.table
containing the estimated value of the quantile used for at-risk-of-poverty threshold estimation.
value
- a data.table
containing the estimated at-risk-of-poverty threshold (in percentage).
lin
- a data.table
containing the linearized variables of the at-risk-of-poverty threshold (in percentage).
