In AWF-GAUG/fisim: Forest Inventory Simulator (fisim) is a package for simulating response and samplign designs common in forest inventories.

Description

Simple random sampling estimator of population means

Usage

est_srs(point_data, est_col = NULL)

Arguments

est_col	A character vector of column names for which estimates are produced. Used when there is more than one way to expand observations from individual sample locations.
data	A data.table object with plot-level information of stand characteristics as coming from the sum_data function.
