%description
Functions which make using the Generalized Regression Estimator(GREG)
J.N.K. Rao, Isabel Molina, (2015) <doi:10.3390/f11020244> and the
Generalized Regression Estimator Operating on Resolutions of Y (GREGORY)
easier. The functions are designed to work well within a forestry context,
and estimate multiple estimation units at once. Compared to other survey
estimation packages, this function has greater flexibility when describing
the linear model.
