I saw some posts like this so I figured I would start my own.

What are some interesting papers in OR that are related to, or even develop, the theory of statistical inference? What are some of the applications that motivate these innovations? How does it relate to more traditional stochastic optimization problems that OR deals with?

I know the classical work was mostly concerned with "applied probability" models (stochastic processes, queuing theory, etc.) but I am personally very interested in statistical inference (asymptotic and finite sample properties of estimators and tests) and being in an OR department I was wondering how most OR people think about this. I know a lot of work now is also on machine learning. Is the field interested in developing inferential methods for these estimators or are they more seen as a means to an end for some forecasting problem? What about questions of causal inference, specifically those developing the theory of causal inference?

I'm going to interpret "in OR" as appearing in OR journals and/or written by people who identify as OR/MS/IE researchers. I'm a bit familiar with the intersection of optimization and statistical estimation. Machine learning, OLS and LAV regression, lasso regression etc. all rely on solving optimization problems to fit models. In addition, optimization models have been proposed for feature selection (choosing which predictors to include in a model) and classification analysis, and I imagine for other types of inference problems.

As far "interesting" papers, that's in the eye of the beholder. One of the seminal papers on optimization models for classification (discriminant analysis) was Mangasarian's 1965 paper in the journal Operations Research [1]. Around 1988, researchers including Fred Glover reopened interest in optimization models for classification, including in a paper in Decision Sciences [2]. Following a workshop in April 1989 at the University of Florida, a number of related papers were published in a special issue of Managerial and Decision Economics, including one by me [3]. (Mine is not overly interesting, but I'll use it to provide the volume information.) Based on the occasional new citation of it, I would say that research on discriminant models continues today (presumably with an improvement in models and heuristics).

I'm less familiar with the work on feature selection (particularly its current state), but I'll toss in a reference to my sole contribution to the area [4], which also ties into discriminant analysis.

One last disclaimer: The question mentions the theory of statistical inference, but most (all?) of the papers I've listed have to do with methods rather than theory.

  • $\begingroup$ Thanks so much for this! Your interpretation of my question was exactly right. I am a little more interested in the theoretical developments that might have been published in OR journals but I think this is an excellent starting point to understand how the broader community thinks about such questions! $\endgroup$
