sae2 (version 1.2-2)

sae2-package: Small Area Estimation: Time-Series Models.

Description

Time series area-level models for small area estimation. The package supplements the functionality of the package sae. Specifically, it includes EBLUP fitting of the Rao-Yu model in the original form without a spatial component. It also offers a modified ("dynamic") version of the Rao-Yu model, replacing the assumption of stationarity. Both univariate and multivariate applications are supported. Of particular note is the allowance for covariance of the area-level sample estimates over time, as encountered in rotating panel designs such as the U.S. National Crime Victimization Survey or present in a time-series of 5-year estimates from the American Community Survey.

The package provides two primary functions, eblupRY and eblupDyn, to fit non-spatial time-series small area models to area-level data. Each acts as an interface to dynRYfit, which offers a number of output options and parameters governing convergence. The function mvrnormSeries provides simulated data under either model. Functions geo_ratios and vcovgen can assist in preparing the input to eblupRY and eblupDyn.
