This CRAN task view contains a list of packages that include
methods typically used in official statistics and survey methodology.
Many packages provide functionality for more than one of the topics listed
below. Therefore this list is not a strict categorization and packages can be
listed more than once. Certain data import/export facilities regarding to often used statistical software tools
like SPSS, SAS or Stata are mentioned in the end of the task view.
Complex Survey Design: Sampling and Sample Size Calculation
- Package sampling includes many different algorithms (Brewer, Midzuno, pps, systematic, Sampford, balanced
(cluster or stratified) sampling via the cube method, etc.) for
drawing survey samples and calibrating the design weights.
- R package surveyplanning includes tools for sample survey planning, including sample size calculation, estimation of expected precision for the estimates of totals, and calculation of optimal sample size allocation.
Package simFrame includes a fast (compiled C-Code) version of

populations with a generalisation of the Lavallee-Hidiroglou method.
Package SamplingStrata offers an approach for choosing the best
stratification of a sampling frame in a multivariate and multidomain setting,
where the sampling sizes in each strata are determined in order to satisfy accuracy
constraints on target estimates.
To evaluate the distribution of target variables in different strata, information of the sampling frame,
or data from previous rounds of the same survey, may be used.
The package BalancedSampling selects balanced and spatially balanced probability samples in multi-dimensional spaces with any prescribed inclusion probabilities. It also includes the local pivot method, the cube and local cube method and a few more methods.

Complex Survey Design: Point and Variance Estimation and Model Fitting
Package survey works with survey samples. It allows to specify a complex survey design (stratified sampling design, cluster sampling, multi-stage sampling and pps
sampling with or without replacement). Once
the given survey design is specified within the function
svydesign(), point and variance estimates can be computed.
The resulting object can be used to estimate (Horvitz-Thompson-) totals, means,
ratios and quantiles for domains or the whole survey sample, and to apply
regression models. Variance estimation for means, totals and ratios can be
done either by Taylor linearization or resampling (BRR, jackkife, bootstrap
- The methods from the survey package are called from package

summarize, and other dplyr-inspired
syntactic style when calculating summary statistics on survey data.
Package convey extends package survey -- see the topic about indicators below.

variance estimators in a simulation environment. It provides a framework for comparing
different point and variance estimators under different survey designs as
well as different conditions regarding missing values, representative and
The lavaan.survey package provides a wrapper function for packages survey and lavaan.
It can be used for
fitting structural equation models (SEM) on samples from complex designs. Using
the design object functionality from package survey, lavaan objects are re-fit
(corrected) with the
lavaan.survey() function of package lavaan.survey.
This allows for the incorporation of clustering, stratification, sampling weights,
and finite population corrections into a SEM analysis.
lavaan.survey() also accommodates
replicate weights and multiply imputed datasets.
Package vardpoor allows to calculate linearisation of several nonlinear population statistics, variance estimation of sample surveys by the ultimate cluster method, variance estimation for longitudinal and cross-sectional measures and measures of change for any stage cluster sampling designs.
The package rpms fits a linear model to survey data in each node obtained by recursively partitioning the data. The algorithm
accounts for one-stage of stratification and clustering as well as unequal probability of selection.
Package svyPVpack extends package survey. This package deals with data
which stem from survey designs and has been created to handle data from large scale
assessments like PISA, PIAAC etc..
Package weights provides a variety of functions for producing simple weighted statistics, such as weighted Pearson's correlations, partial correlations, Chi-Squared statistics, histograms and t-tests.
Complex Survey Design: Calibration
Package survey allows for post-stratification, generalized
raking/calibration, GREG estimation and trimming of weights.

calibrate for nonresponse (with response homogeneity groups) for stratified
calibWeights() function in package laeken is a
possible faster (depending on the example) implementation of parts of

the selective occurrence of missing values, and the distribution of correlated variables.
Package treemap provide treemaps. A treemap is a space-filling visualization of aggregates of data with
hierarchical structures. Colors can be used to relate to highlight differences between comparable aggregates.
A distinction between iterative model-based methods, k-nearest neighbor methods
and miscellaneous methods is made. However, often the criteria for using a
method depend on the scale of the data, which in official statistics are
typically a mixture of continuous, semi-continuous, binary, categorical and
count variables. In addition, measurement errors may corrupt non-robust imputation methods.
Note that only few imputation methods can deal with mixed types of variables and only few methods account for robustness issues.

Package missForest uses the functionality of the randomForest to impute missing values in an iterative single-imputation fashion. It can deal with almost any kind of variables except semi-continuous ones. Even the underlying bootstrap approach of random forests ensures that from multiple runs one can get multiple imputations but the additional uncertainty of imputation is only considered when choosing the random forest method of package mice.
Nearest Neighbor Imputation Methods
Package VIM provides an implementation of the popular
sequential and random (within a domain) hot-deck algorithm.

Copula-based Imputation Methods:
The S4 class package CoImp imputes multivariate missing data by using conditional copula functions. The imputation procedure is semiparametric: the margins are non-parametrically estimated through local likelihood of low-degree polynomials while a range of different parametric models for the copula can be selected by the user. The missing values are imputed by drawing observations from the conditional density functions by means of the Hit or Miss Monte Carlo method. It works either for a matrix of continuous scaled variables or a matrix of discrete distributions.

by principal component analysis (PCA) or categorical variables by multiple
correspondence analysis (MCA).

Package VIM allows to visualize the structure of missing values
using suitable plot methods. It also comes with a graphical user interface.
