Leonard J. Savage

Leonard J. Savage was an influential statistician and philosopher known for his work on decision theory and the foundations of probability. He introduced the concept of subjective probability, which suggests that probabilities reflect personal beliefs about uncertain events rather than just long-term frequencies. Savage's ideas bridged mathematics and real-world decision-making, providing rigorous methods to evaluate choices under uncertainty. His book, "The Foundations of Statistics," laid the groundwork for modern statistical inference, emphasizing rational decision-making based on individual judgment and evidence. His work significantly impacted economics, statistics, and the philosophy of probability.
