or Not : A Tale of Three Algorithms for Streaming: Covariance Estimation after Welford and Chan-Golub-LeVeque
Felix Reichel
We place three algorithms for computing the unbiased sample covariance matrix in streaming and distributed settings on a common algebraic, numerical, and statistical foundation. Th…
High-Performance Variance-Covariance Matrix Construction Using an Uncentered Gram Formulation
Felix Reichel
Reichel (2025) defined the bariance as a pairwise-difference measure that can be rewritten in linear time using only scalar sums. We extend this idea to the covariance matrix by sh…
Price Pass-Through of Austria's Single-Use Plastics Producer Charges: Evidence from Retail Offer Spells
Felix Reichel
Single use plastics (SUPs) impose substantial environmental costs. Following Directive (EU) 2019/904, Austria introduced producer charges and mandatory participation in collection…
Two-Stage Asymmetric Tullock Contests with Cost Shifters and Endogenous Continuation Decision
Felix Reichel
This paper introduces a contest-theoretic simplified model of triathlon as a sequential two-stage game. In Stage 1 (post-swim), participants decide whether to continue or withdraw…
Statistically Significant Linear Regression Coefficients Solely Driven By Outliers In Finite-sample Inference
Felix Reichel
In this paper, we investigate the impact of outliers on the statistical significance of coefficients in linear regression. We demonstrate, through numerical simulation using R, tha…
Strategic Effort and Non-Linear Positional Bandwagon Drafting Benefits in Multi-Stage Competitive Games: Evidence from Triathlon
Felix Reichel
This paper examines strategic effort and positioning choices in finite multistage games These choices can generate positional bandwagon drafting benefits through externalities when…
