Description

Calculate means for the NWOS.

Usage

1
nwos_mean(weight, area = 1, domain = 1, variable)

Arguments

weight

vector of weights.

area

vector of area (e.g., forest acres in the stratum). Default = 1 (i.e., estimates are in terms of ownerships).

domain

binary vector (i.e., dummay variable) with 1 indicating inclusion in the domain of interest and 0 otherwise. Default = 1 (i.e., all ownerships are included).

variable

vector of values for the variable of interest.

Details

This function needs to be run by stratum (e.g., family forest ownerships in a state).

Value

Mean of variable of interest.
