Base R ships with a lot of functionality useful for computational
econometrics, in particular in the stats package. This
functionality is complemented by many packages on CRAN, a brief overview
is given below. There is also a considerable overlap between the tools
for econometrics in this view and those in the task views on
Finance, SocialSciences, and TimeSeries.
is a suitable mailing list for obtaining help
and discussing questions about both computational finance and econometrics.
The packages in this view can be roughly structured into the following topics.
If you think that some package is missing from the list, please contact the maintainer.
Basic linear regression
- Estimation and standard inference: Ordinary least squares (OLS) estimation for linear models is provided
lm() (from stats) and standard tests for model comparisons are available in various
methods such as
- Further inference and nested model comparisons: Functions analogous to
that also support asymptotic tests (z instead of t tests, and
Chi-squared instead of F tests) and plug-in of other covariance
waldtest() in lmtest.
Tests of more general linear hypotheses are implemented in
and for nonlinear hypotheses in
deltaMethod() in car.
- Robust standard errors: HC, HAC, clustered, and bootstrap covariance matrices are
available in sandwich and can be plugged into the inference functions mentioned above.
- Nonnested model comparisons: Various tests for comparing non-nested linear
models are available in lmtest (encompassing test, J test, Cox test).
The Vuong test for comparing other non-nested models is provided by nonnest2
(and specifically for count data regression in pscl).
- Diagnostic checking: The packages
car and lmtest provide a large collection
of regression diagnostics and diagnostic tests.
- Generalized linear models (GLMs): Many standard microeconometric models belong to the
family of generalized linear models and can be fitted by
from package stats. This includes in particular logit and probit models
for modeling choice data and Poisson models for count data. Effects for typical
values of regressors in these models can be obtained and visualized using effects.
Marginal effects tables for certain GLMs can be obtained using the
mfx and margins packages. Interactive visualizations of both effects and marginal
effects are possible in LinRegInteractive.
- Binary responses: The standard logit and probit models (among many others) for binary
responses are GLMs that can be estimated by
family = binomial.
Bias-reduced GLMs that are robust to complete and quasi-complete separation are provided by
brglm. Discrete choice models estimated by simulated maximum likelihood are
implemented in Rchoice. bife provides binary choice models with fixed effects.
Heteroscedastic probit models (and other heteroscedastic
GLMs) are implemented in glmx along with parametric link functions and goodness-of-link
tests for GLMs.
- Count responses: The basic Poisson regression is a GLM that can be estimated by
family = poisson as explained above.
Negative binomial GLMs are available via
glm.nb() in package MASS.
Another implementation of negative binomial models
is provided by aod, which also contains other models for overdispersed
data. Zero-inflated and hurdle count models are provided in package pscl.
A reimplementation by the same authors is currently under development in countreg
on R-Forge which also encompasses separate functions for zero-truncated regression,
finite mixture models etc.
- Multinomial responses: Multinomial models
with individual-specific covariates only are available in
from package nnet. An implementation with both individual- and
choice-specific variables is mlogit. Generalized
multinomial logit models (e.g., with random effects etc.) are in gmnl.
Generalized additive models
(GAMs) for multinomial responses can be fitted with the VGAM package.
A Bayesian approach to multinomial probit models is provided by MNP.
Various Bayesian multinomial models (including logit and probit) are available
in bayesm. Furthermore, the package RSGHB fits various
hierarchical Bayesian specifications based on direct specification of the likelihood
- Ordered responses: Proportional-odds regression for ordered responses is implemented
polr() from package MASS. The package ordinal
provides cumulative link models for ordered data which encompasses proportional
odds models but also includes more general specifications. Bayesian ordered probit
models are provided by bayesm.
- Censored responses: Basic censored regression models (e.g., tobit models)
can be fitted by
survreg() in survival, a convenience
tobit() is in package AER. Further censored
regression models, including models for panel data, are provided in censReg.
Interval regression models are in intReg. Censored regression models with
conditional heteroscedasticity are in crch.
Models for sample selection are available in sampleSelection
and semiparametric extensions of these are provided by SemiParSampleSel.
Package matchingMarkets corrects for selection bias when the sample is the
result of a stable matching process (e.g., a group formation or college admissions problem).

Gaussian, logistic, and t responses. Homoscedastic Gaussian responses are also available in

the constant elasticity of scale (CES) function is in micEconCES;
the symmetric normalized quadratic profit (SNQP) function is in micEconSNQP.
The almost ideal demand system (AIDS) is in micEconAids.
Stochastic frontier analysis (SFA) is in frontier and certain special cases also in sfa.
Semiparametric SFA in is available in semsfa and spatial SFA in spfrontier and ssfa.

is provided by
ivreg() in AER. Other implementations are in

focus on multiple group fixed effects).
- Binary responses: An IV probit model via GLS estimation
is available in ivprobit. The LARF package estimates
local average response functions for binary treatments and binary instruments.

with standard 2SLS functions (see above). Dedicated IV panel data models are provided
by ivfixed (fixed effects) and ivpanel (between and random effects).
REndo fits linear models with endogenous regressor using various latent instrumental variable approaches.
ivlewbel implements the Lewbel approach based on GMM estimation of triangular systems using heteroscedasticity-based IVs.
Panel data models
- Panel standard errors: A simple approach for panel data is
to fit the pooling (or independence) model (e.g., via
and only correct the standard errors. Different types of clustered, panel, and panel-corrected
standard errors are available in sandwich (incorporating prior work from multiwayvcov),
clusterSEs, pcse, clubSandwich, plm,
and geepack, respectively. The latter two require estimation of the
pooling/independence models via
the respective packages (which also provide other types of models, see below).
- Linear panel models: plm, providing a wide range of within,
between, and random-effect methods (among others) along with corrected standard
errors, tests, etc. Another implementation of several of these models is in
Paneldata. Various dynamic panel models are available in plm
and dynamic panel models with fixed effects in OrthoPanels.
Panel vector autoregressions are implemented in panelvar.
- Generalized estimation equations and GLMs: GEE models for panel data (or longitudinal
data in statistical jargon) are in geepack. The pglm package provides
estimation of GLM-like models for panel data.

general multi-level data) are available in lme4 and nlme.

analyzing panel data with large dimensions n and T and can be considered when
the unobserved heterogeneity effects are time-varying.

latter using a GMM approach). splm is a package for spatial panel
models. Spatial probit models are available in spatialprobit.

information about both basic time series infrastructure and time series models.

Time series models for financial econometrics (e.g., GARCH, stochastic volatility models, or
stochastic differential equations, etc.) are described in the Finance task view.
- Infrastructure for regularly spaced time series: The class
"ts" in package stats is R's standard class for
regularly spaced time series (especially annual, quarterly, and monthly data). It can be
coerced back and forth without loss of information to
from package zoo.
- Infrastructure for irregularly spaced time series: zoo provides infrastructure for
both regularly and irregularly spaced time series (the latter via the class
"zoo") where the time information can be of arbitrary class.
This includes daily series (typically with
"Date" time index)

time index is xts. Further packages aimed particularly at
finance applications are discussed in the Finance task view.
