Abstract:
|
In the 2005 National Resources Inventory, a longitudinal survey of the land area of the United States, an experiment was conducted to calibrate a new method for measuring developed land against the standard survey protocol. Estimated Generalized Least Squares estimators based on a direct estimator of the covariance matrix proved to be unstable at small sample sizes. A related problem arises in the analysis of longitudinal data or complex survey data. The efficiencies of estimators of the regression coefficients in a linear model constructed with different estimators of the covariance matrix are compared through simulation.
