摘要:To measure income inequality with right censored (topcoded) data, we propose
multiple imputation for censored observations using draws from Generalized Beta
of the Second Kind distributions to provide partially synthetic datasets
analyzed using complete data methods. Estimation and inference uses Reiter's
(Survey Methodology 2003) formulae. Using Current Population Survey (CPS)
internal data, we find few statistically significant differences in income
inequality for pairs of years between 1995 and 2004. We also show that using CPS
public use data with cell mean imputations may lead to incorrect inferences
about inequality differences. Multiply-imputed public use data provide an
intermediate solution.
