se.avg {hfr}

Calculate approximate standard errors for a fitted HFR model

Description

This function computes the weighted average standard errors across levels using Burnham & Anderson (2004).

Usage

se.avg(object)

Arguments

object

Fitted hfr model.

Details

The HFR computes linear regressions over several levels of an estimated hierarchy. By averaging the standard errors across hierarchical levels, an indication can be obtained about the average significance of the variables.

Standard errors are understated, since the uncertainty in the hierarchy estimation is not reflected.

Value

A vector of standard errors.
