Package Overview

Description

A key design pattern of the package is that the majority of the estimating methods is available in two "flavors":

  • bare-bone methods

  • survey methods

Bare-bone methods are stripped-down versions of the survey methods in terms of functionality and informativeness. These functions may serve users and package developers as building blocks. In particular, bare-bone functions cannot compute variances.

The survey methods are much more capable and depend, for variance estimation, on the survey package.

Basic Robust Estimators

Trimming

  • Bare-bone methods: weighted_mean_trimmed and weighted_total_trimmed

  • Survey methods: svymean_trimmed and svytotal_trimmed

Winsorization

  • Bare-bone methods:

    • weighted_mean_winsorized and weighted_total_winsorized

    • weighted_mean_k_winsorized and weighted_total_k_winsorized

  • Survey methods:

    • svymean_winsorized and svytotal_winsorized

    • svymean_k_winsorized and svytotal_k_winsorized

Dalen's estimators (weight reduction methods)

  • Bare-bone methods: weighted_mean_dalen and weighted_total_dalen

  • Survey methods: svymean_dalen and svytotal_dalen

M-estimators

  • Bare-bone methods:

    • weighted_mean_huber and weighted_total_huber

    • weighted_mean_tukey and weighted_total_tukey

    • huber2 (weighted Huber Proposal 2 estimator)

  • Survey methods:

    • svymean_huber and svytotal_huber

    • svymean_tukey and svytotal_tukey

    • mer (minimum estimated risk estimator)

Survey Regression (weighted least squares)

svyreg

Robust Regression and Ratio Estimation (weighted)

  • Regression M-estimators: svyreg_huberM and svyreg_tukeyM

  • Regression GM-estimators (Mallows and Schweppe): svyreg_huberGM and svyreg_tukeyGM

  • Ratio M-estimators: svyratio_huber and svyratio_tukey

Robust Generalized Regression (GREG) and Ratio Prediction of the Population Mean and Total

  • Regression predictors: svymean_reg and svytotal_reg

  • Ratio predictors: svymean_ratio and svytotal_ratio

Utility functions

  • weighted_quantile and weighted_median

  • weighted_mad and weighted_IQR

  • weighted_mean and weighted_total

  • weighted_line, weighted_median_line, and weighted_median_ratio
