Programming your own R packages offers many benefits to both developers and users, and is a major reason for the high level of importance of R within the data science community. Details. ↑An alternative option is discussed here but it is less powerful than the sandwich package. Package ‘robust’ February 24, 2013 Version 0.4-11 Date 2013-02-23 Title Robust Library Description A package of robust methods. The examples shown here have presented R code for M estimation. We include two functions that implement means estimators, difference_in_means() and horvitz_thompson(), and three linear regression estimators, lm_robust(), lm_lin(), and iv_robust(). Details. The method uses the ordinary estimates of regression coefficients and other parameters of the model, but involves correcting the covariance matrix for model misspecification and sampling design. This includes methodology for model selection and multivariate statistics. In other words, it is an observation whose dependent-variablevalue is unusual given its value on the predictor variables. Robust regression. The robustbase R package provides tools that analyze data with robust methods. This includes regression methodology including model selections and multivariate statistics where we strive to cover the book "Robust Statistics, Theory and Methods" by 'Maronna, Martin and Yohai'; Wiley 2006. Your email address will not be published. I am trying to learn R after using Stata and I must say that I love it. You also need some way to use the variance estimator in a linear model, and the lmtest package is the solution. [! Examples of usage can be seen below and in the Getting Started vignette. It implements robust t-tests (independent and dependent samples), robust ANOVA (including between-within subject designs), quantile ANOVA, robust correlation, robust mediation, and nonparametric ANCOVA models based on robust location measures.

There are other estimation options available in rlm and other R commands and packages: Least trimmed squares using ltsReg in the robustbase package and MM using rlm. Using "HC1" will replicate the robust standard errors you would obtain using STATA. In this section, we will present some packages that contain valuable resources for regression analysis. This includes methodology for model selection and multivariate statistics. "Essential" Robust Statistics. It takes a formula and data much in the same was as lm does, and all auxiliary variables, such as clusters and weights, can be passed either as quoted names of columns, as bare column names, or as a self-contained vector. The rdrobust package provides Stata and R implementations of statistical inference and graphical procedures for Regression Discontinuity designs employing local polynomial and partitioning methods. Regressors and instruments should be specified in a two-part formula, such as y ~ x1 + x2 | z1 + z2 + z3, where x1 and x2 are regressors and z1, z2, and z3 are instruments. This formula fits a linear model, provides a variety ofoptions for robust standard errors, and conducts coefficient tests References. Tools allowing to analyze data with robust methods. As you can see it produces slightly different results, although there is no change in the substantial conclusion that you should not omit these two variables as the null hypothesis that both are irrelevant is soundly rejected. The syntax is similar to that in ivreg from the AER package. Previously, we have mentioned the R packages, which allow us to access a series of features to solve a specific problem. Author Jiahui Wang, Ruben Zamar , Alfio Marazzi Subscribe to my free statistics newsletter. You can easily estimate heteroskedastic standard errors, clustered standard errors, and classical standard errors. The robustbase R package provides tools that analyze data with robust methods. The input vcov=vcovHCinstructs R to use a robust version of the variance covariance matrix. In general, R is pretty well endowed with all sorts of robust regression functions and packages such as rlm in MASS (Venables and Ripley2002), and lmrob and nlrob in robustbase (Rousseeuw, Croux, Todorov, Ruckstuhl, Salibian-Barrera, Verbeke, Koller, and Maechler2015).
