Model-Based Inference and Experimental Design for Interference Using Partial Network Data

no code implementations17 Jun 2024 Steven Wilkins Reeves, Shane Lubold, Arun G. Chandrasekhar, Tyler H. McCormick

The stable unit treatment value assumption states that the outcome of an individual is not affected by the treatment statuses of others, however in many real world applications, treatments can have an effect on many others beyond the immediately treated.

Robustly estimating heterogeneity in factorial data using Rashomon Partitions

2 code implementations2 Apr 2024 Aparajithan Venkateswaran, Anirudh Sankar, Arun G. Chandrasekhar, Tyler H. McCormick

Many statistical analyses, in both observational data and randomized control trials, ask: how does the outcome of interest vary with combinations of observable covariates?

Non-robustness of diffusion estimates on networks with measurement error

no code implementations8 Mar 2024 Arun G. Chandrasekhar, Paul Goldsmith-Pinkham, Tyler H. McCormick, Samuel Thau, Jerry Wei

First, we show that even when measurement error is vanishingly small, such that the share of missed links is close to zero, forecasts about the extent of diffusion will greatly underestimate the truth.

Identifying the latent space geometry of network models through analysis of curvature

1 code implementation19 Dec 2020 Shane Lubold, Arun G. Chandrasekhar, Tyler H. McCormick

A common approach to modeling networks assigns each node to a position on a low-dimensional manifold where distance is inversely proportional to connection likelihood.

Tractable and Consistent Random Graph Models

1 code implementation27 Oct 2012 Arun G. Chandrasekhar, Matthew O. Jackson

We define a general class of network formation models, Statistical Exponential Random Graph Models (SERGMs), that nest standard exponential random graph models (ERGMs) as a special case.
