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.
Furthermore, the
Finance SIG
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
by
lm()
(from stats) and standard tests for model comparisons are available in various
methods such as
summary()
and
anova().

Further inference and nested model comparisons
: Functions analogous to
the basic
summary()
and
anova()
methods
that also support asymptotic tests (
z
instead of
t
tests, and
Chisquared instead of
F
tests) and plugin of other covariance
matrices are
coeftest()
and
waldtest()
in
lmtest.
Tests of more general linear hypotheses are implemented in
linearHypothesis()
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 nonnested linear
models are available in
lmtest
(encompassing test, J test, Cox test).
The Vuong test for comparing other nonnested 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.
Microeconometrics

Generalized linear models (GLMs)
: Many standard microeconometric models belong to the
family of generalized linear models and can be fitted by
glm()
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.

responses are GLMs that can be estimated by
glm()
with
family = binomial.
Biasreduced GLMs that are robust to complete and quasicomplete 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

along with parametric link functions and goodnessoflink
tests for GLMs.

Count responses

is provided by
aod, which also contains other models for overdispersed
data. Zeroinflated and hurdle count models are provided in package

A reimplementation by the same authors is currently under development in
countreg
on RForge which also encompasses separate functions for zerotruncated regression,
finite mixture models etc.

Multinomial responses

with individualspecific covariates only are available in
multinom()
from package
nnet. Implementations with both individual and
choicespecific variables are

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
function.

Ordered responses
: Proportionalodds regression for ordered responses is implemented
in
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
interface

Panel data models

Panelcorrected standard errors

to fit the pooling (or independence) model (e.g., via
lm()
or
glm())
and only correct the standard errors. Different types of panelcorrected standard
errors are available in
multiwayvcov,
clusterSEs,
pcse,
clubSandwich,
plm,
and
geepack, respectively. The latter two require estimation of the
pooling/independence models via

from
the respective packages (which also provide other types of models, see below).

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"

regularly spaced time series (especially annual, quarterly, and monthly data). It can be
coerced back and forth without loss of information to
"zooreg"
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

time index)
or intraday series (e.g., with
"POSIXct"
time index). An extension
based on
zoo
geared towards time series with different kinds of
time index is

finance applications are discussed in the
Finance
task view.

Classical time series models
: Simple autoregressive models can be estimated
