Summarize the variance estimation method for the survey design

Description

Summarize the variance estimation method for the survey design

Usage

get_variance_method(survey_design)

Arguments

survey_design

A survey design object created with the survey package.

Details

For replicate designs, the type of replicates will be determined based on the 'type' element of the survey design object. If type = 'bootstrap', this can correspond to any of various types of bootstrap replication (Canty-Davison bootstrap, Rao-Wu's (n-1) bootstrap, etc.).

For designs which use linearization-based variance estimation, the summary only indicates that linearization is used for variance estimation and, if a special method is used for PPS variance estimation (e.g. Overton's approximation), that PPS variance estimation method will be described.

Value

A text string describing the method used for variance estimation
