John Wishart

John Wishart was a Scottish mathematician and statistician, best known for his work in statistical theory, particularly for developing the Wishart distribution, a probability distribution important in multivariate statistics. This distribution deals with random matrices and has applications in various fields such as finance, biology, and machine learning, especially in the analysis of data with multiple variables. His contributions have significantly influenced statistical methodology, helping researchers understand the relationships between different data points and guiding data analysis in many practical situations.
