Abstract: This article deals with a risk probability minimization problem for finite horizon continuous-time Markov decision processes with unbounded transition rates and history-dependent policies.

Imagine you and I decide to play a simple game of chance. We each throw $50 into a pot and start flipping a coin. Heads, you get a point; tails, I get one. The first person to reach 10 points walks ...

Native Americans have been playing with dice in games of chance for more than 12,000 years, according to a new paper published in the journal American Antiquity. And the oldest examples of Native ...

Most optimization problems in control theory assume you're working in flat space. You have a system, you want to steer it from one state to another, and you minimize some cost along the way. This ...

Sometimes in a comparison of the frequency of observations in a fourfold table the numbers are too small for the χ² test (Chapter 8). The exact probability test devised by Fisher, Irwin, and Yates (1) ...

Probability is a fundamental concept in mathematics and statistics that deals with the likelihood of events occurring. It provides a framework for quantifying uncertainty and making predictions based ...

Augmented inverse probability weighting (AIPW) is a doubly robust estimator for causal inference. The AIPW package is designed for estimating the average treatment effect of a binary exposure on risk ...
