Modeling and Analyzing Urban Networks and Amenities With OSMnx

open access: yesGeographical Analysis, EarlyView.
ABSTRACT OSMnx is a Python package for downloading, modeling, analyzing, and visualizing urban networks and any other geospatial features from OpenStreetMap data. A large and growing body of literature uses it to conduct scientific studies across the disciplines of geography, urban planning, transport engineering, computer science, and others.

Medical Knowledge Integration Into Reinforcement Learning Algorithms for Dynamic Treatment Regimes

open access: yesInternational Statistical Review, EarlyView.
Summary The goal of precision medicine is to provide individualised treatment at each stage of chronic diseases, a concept formalised by dynamic treatment regimes (DTR). These regimes adapt treatment strategies based on decision rules learned from clinical data to enhance therapeutic effectiveness.

The Role of Dice in the Emergence of the Probability Calculus

open access: yesInternational Statistical Review, EarlyView.
Summary The early development of the probability calculus was clearly influenced by the roll of dice. However, while dice have been cast since time immemorial, documented calculations on the frequency of various dice throws date back only to the mid‐13th century.

Firm Disclosures, Uncertain Profits, and (Indirectly) Priced Idiosyncratic Volatility

open access: yesJournal of Business Finance &Accounting, EarlyView.
ABSTRACT We show that the negative relation between idiosyncratic volatility (IVOL) and expected returns exists only among firms with low profitability and high uncertainty about profitability. We propose an incomplete information model in which agents cannot disentangle systematic from idiosyncratic shocks.
