WebMar 2, 2024 · Network Cluster-Robust Inference. Since network data commonly consists of observations from a single large network, researchers often partition the network into clusters in order to apply cluster-robust inference methods. Existing such methods require clusters to be asymptotically independent. Under mild conditions, we prove that, for this ... WebA key component of empirical research is conducting accurate statistical inference. One challenge to this is the possibility of clustered (or non-independent) errors. In this paper …

WebJan 1, 2012 · In this article we propose a variance estimator for the OLS estimator as well as for nonlinear estimators such as logit, probit, and GMM. This variance estimator enables cluster-robust inference when there is two-way or multiway clustering that is nonnested.
WebNov 1, 2024 · As a cure, we propose robust inference based on the balanced regression model, where the lagged regressor and the lagged dependent variable are augmented to the original regression. The induced t -statistic via such an augmentation is shown to be asymptotically standard normal and is therefore free of nuisance parameters, which turns … WebMay 6, 2024 · Methods for cluster-robust inference are routinely used in economics and many other disciplines. However, it is only recently that theoretical foundations for the use of these methods in many empirically relevant situations have been developed. In this paper, we use these theoretical results to provide a guide to empirical practice.

Robust statistical methods have been developed for many common problems, such as estimating location, scale, and regression parameters. One … See more Robust statistics seek to provide methods that emulate popular statistical methods, but are not unduly affected by outliers or other small departures from model assumptions. In statistics, classical estimation methods … See more There are various definitions of a "robust statistic." Strictly speaking, a robust statistic is resistant to errors in the results, produced by deviations from assumptions (e.g., of normality). This means that if the assumptions are only approximately met, the robust estimator … See more The basic tools used to describe and measure robustness are the breakdown point, the influence function and the sensitivity curve. See more A pivotal quantity is a function of data, whose underlying population distribution is a member of a parametric family, that is not dependent on the values of the parameters. An ancillary statistic is such a function that is also a statistic, meaning that it is computed … See more The mean is not a robust measure of central tendency. If the dataset is e.g. the values {2,3,5,6,9}, then if we add another datapoint with value -1000 or +1000 to the data, the resulting mean will be very different to the mean of the original data. Similarly, if we … See more (The mathematical context of this paragraph is given in the section on empirical influence functions.) Historically, several approaches to robust estimation were proposed, including R-estimators and L-estimators. However, M-estimators now … See more Replacing missing data is called imputation. If there are relatively few missing points, there are some models which can be used to estimate values to complete the series, such as replacing missing values with the mean or median of the data.
