Abstract:	The properties of a replication variance estimation method for the two-phase regression estimator is described. The procedure reproduces the estimated variance of the first-phase sample for those attributes of the first-phase sample used as controls for the second-phase sample. Only the second-phase sample is required by the analyst for variance estimation. The procedure is applied to the National Resources Inventory, a study of land use based on a large area sample of the United States.
