%description
Estimation of the generalized beta distribution of the second kind (GB2)
and related models using grouped data in form of income shares. The GB2
family is a general class of distributions that provides an accurate fit
to income data. 'GB2group' includes functions to estimate the GB2, the
Singh-Maddala, the Dagum, the Beta 2, the Lognormal and the Fisk
distributions. 'GB2group' deploys two different econometric strategies to
estimate these parametric distributions, the equally weighted minimum
distance (EWMD) estimator and the optimally weighted minimum distance
(OMD) estimator. Asymptotic standard errors are reported for the OMD
estimates. Standard errors of the EWMD estimates are obtained by Monte
Carlo simulation. See Jorda et al. (2018) <arXiv:1808.09831> for a
detailed description of the estimation procedure.
