FIA Sample Plot-Level Data for Idaho

datasets

A set of model-assisted survey estimators and corresponding
variance estimators for single stage, unequal probability, without replacement
sampling designs. All of the estimators can be written as a generalized
regression estimator with the Horvitz-Thompson, ratio, post-stratified, and
regression estimators summarized by Sarndal et al. (1992, ISBN:978-0-387-40620-6).
Two of the estimators employ a statistical learning model as the assisting model:
the elastic net regression estimator, which is an extension of the lasso regression
estimator given by McConville et al. (2017) <doi:10.1093/jssam/smw041>, and the
regression tree estimator described in McConville and Toth (2017) <arXiv:1712.05708>.
The variance estimators which approximate the joint inclusion probabilities can
be found in Berger and Tille (2009) <doi:10.1016/S0169-7161(08)00002-3> and the
bootstrap variance estimator is presented in Mashreghi et al. (2016)
<doi:10.1214/16-SS113>.
