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 and HAC 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).
- Diagnost checking: The packages
car and lmtest provide a large collection
of regression diagonstics 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 package. 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. Heteroskedastic probit models (and other heteroskedastic
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. Implementations with both individual- and
choice-specific variables are mlogit and mnlogit. 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.

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.

by ivfixed (fixed effects) and ivpanel (between and random effects).
ivbma estimates Bayesian IV models with conditional Bayes factors.
ivlewbel implements the Lewbel approach based on GMM estimation of triangular systems using heteroscedasticity-based IVs.
Panel data models
- Panel-corrected 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 panel-corrected standard
errors are available in multiwayvcov, pcse, 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).

between, and random-effect methods (among others) along with corrected standard
errors, tests, etc. Another implementation of several of these models is in

data in statistical jargon) are in geepack. The pglm package provides
estimation of GLM-like models for panel data.
- Mixed effects models: Linear and nonlinear models for panel data (and more
general multi-level data) are available in lme4 and nlme.

Time series data and models
- The TimeSeries task view provides much more detailed
information about both basic time series infrastructure and time series models.
Here, only the most important aspects relating to econometrics are briefly mentioned.
Time series models for financial econometrics (e.g., GARCH, stochastic volatility models, or
stochastic differential equations, etc.) are described in the Finance.
- 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)
or intra-day series (e.g., with
"POSIXct" time index). An extension
based on zoo geared towards time series with different kinds of
time index is xts. Further packages aimed particularly at
finance applications are discussed in the Finance task view.
- Classical time series models: Simple autoregressive models can be estimated
ar() and ARIMA modeling and Box-Jenkins-type analysis can be
carried out with
arima() (both in the stats package). An enhanced
arima() is in forecast.

- Structural time series models: Standard models can be fitted with
StructTS() in stats.
Further packages are discussed in the TimeSeries task view.
