Y 
Study variable (for example equalized disposable income or gross pension income). One dimensional object convertible to onecolumn 
w_final 
Weight variable. One dimensional object convertible to onecolumn 
age 
Age variable. One dimensional object convertible to onecolumn 
pl085 
Retirement variable (Number of months spent in retirement or early retirement). One dimensional object convertible to onecolumn 
month_at_work 
Variable for total number of month at work (sum of the number of months spent at fulltime work as employee, number of months spent at parttime work as employee, number of months spent at fulltime work as selfemployed (including family worker), number of months spent at parttime work as selfemployed (including family worker)). One dimensional object convertible to onecolumn 
Y_den 
Denominator variable (for example gross individual earnings). One dimensional object convertible to onecolumn 
Y_thres 
Variable (for example equalized disposable income) used for computation and linearization of poverty threshold. One dimensional object convertible to onecolumn 
wght_thres 
Weight variable used for computation and linearization of poverty threshold. One dimensional object convertible to onecolumn 
ID_level1 
Variable for level1 ID codes. One dimensional object convertible to onecolumn 
ID_level2 
Optional variable for unit ID codes. One dimensional object convertible to onecolumn 
H 
The unit stratum variable. One dimensional object convertible to onecolumn 
PSU 
Primary sampling unit variable. One dimensional object convertible to onecolumn 
N_h 
Number of primary sampling units in population for each stratum (and period if Optional for singlestage sampling design as it will be estimated from sample data. Recommended for multistage sampling design as If If 
PSU_sort 
optional; if PSU_sort is defined, then variance is calculated for systematic sample. 
fh_zero 
by default FALSE; fh is calculated as division of n_h and N_h in each strata, if true, fh value is zero in each strata. 
PSU_level 
by default TRUE; if PSU_level is true, in each strata fh is calculated as division of count of PSU in sample (n_h) and count of PSU in frame(N_h). if PSU_level is false, in each strata fh is calculated as division of count of units in sample (n_h) and count of units in frame(N_h), which calculated as sum of weights. 
sort 
Optional variable to be used as tiebreaker for sorting. One dimensional object convertible to onecolumn 
Dom 
Optional variables used to define population domains. If supplied, variables is calculated for each domain. An object convertible to 
period 
Optional variable for survey period. If supplied, variables is calculated for each time period. Object convertable to 
gender 
Numerical variable for gender, where 1 is for males, but 2 is for females. One dimensional object convertible to onecolumn 
dataset 
Optional survey data object convertible to 
X 
Optional matrix of the auxiliary variables for the calibration estimator. Object convertible to 
periodX 
Optional variable of the survey periods. If supplied, residual estimation of calibration is done independently for each time period. Object convertible to 
X_ID_level1 
Variable for level1 ID codes. One dimensional object convertible to onecolumn 
ind_gr 
Optional variable by which divided independently X matrix of the auxiliary variables for the calibration. One dimensional object convertible to onecolumn 
g 
Optional variable of the g weights. One dimensional object convertible to onecolumn 
q 
Variable of the positive values accounting for heteroscedasticity. One dimensional object convertible to onecolumn 
datasetX 
Optional survey data object in household level convertible to 
percentage 
A numeric value in range [0,100] for p in the formula for 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 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. 
alpha 
a numeric value in range [0,100] for the order of the income quantile share ratio (in percentage). 
confidence 
Optional positive value for confidence interval. This variable by default is 0.95. 
outp_lin 
Logical value. If 
outp_res 
Logical value. If 
type 
a character vector (of length one unless several.ok is TRUE), example "linarpr","linarpt", "lingpg", "linpoormed", "linrmpg", "lingini", "lingini2", "linqsr", "linarr", "linrmir".
