Calculate means for the NWOS.

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

`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. |

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

Mean of variable of interest.
