Estimate the Watts (1968) poverty measure and its components
svywattsdec(formula, design, ...) ## S3 method for class 'survey.design' svywattsdec( formula, design, type_thresh = "abs", abs_thresh = NULL, percent = 0.6, quantiles = 0.5, na.rm = FALSE, thresh = FALSE, ... ) ## S3 method for class 'svyrep.design' svywattsdec( formula, design, type_thresh = "abs", abs_thresh = NULL, percent = 0.6, quantiles = 0.5, na.rm = FALSE, thresh = FALSE, ... ) ## S3 method for class 'DBIsvydesign' svywattsdec(formula, design, ...)
formula |
a formula specifying the income variable |
design |
a design object of class |
... |
additional arguments. Currently not used. |
type_thresh |
type of poverty threshold. If "abs" the threshold is fixed and given the value of abs_thresh; if "relq" it is given by percent times the quantile; if "relm" it is percent times the mean. |
abs_thresh |
poverty threshold value if type_thresh is "abs" |
percent |
the multiple of the the quantile or mean used in the poverty threshold definition |
quantiles |
the quantile used used in the poverty threshold definition |
na.rm |
Should cases with missing values be dropped? |
thresh |
return the poverty threshold value |
you must run the convey_prep
function on your survey design object immediately after creating it with the svydesign
or svrepdesign
function.
Object of class "cvydstat
", with estimates for the Watts index, FGT(0), Watts Poverty Gap Ratio, and Theil(poor incomes) with a "var
" attribute giving the variance-covariance matrix.
A "statistic
" attribute giving the name of the statistic.
This function is experimental and is subject to change in later versions.
