Probability and Multivariate Distributions for Mathematical Statistics

Understanding how multiple random variables interact is a cornerstone of advanced statistical analysis and mathematical statistics exams. This text-based course offers a clear, structured path to mastering probability theory and multivariate distributions from the ground up. Through detailed written explanations and step-by-step mathematical proofs, you will transition from basic probability concepts to analyzing complex multi-dimensional distribution models. You will learn to calculate joint probabilities, find marginal and conditional distributions, and apply transformation techniques with confidence. What you'll learn: 1. Understand foundational probability concepts, random variables, and expectation basics. 2. Analyze joint, marginal, and conditional probability density functions. 3. Master the properties of multivariate normal distributions and covariance matrices. 4. Apply transformation of variables techniques to find distributions of functions of random variables. 5. Evaluate limit theorems, including the Central Limit Theorem and the Law of Large Numbers. 6. Explore modern statistical computing applications using basic distribution modeling concepts. The course begins with essential probability definitions and single-variable distributions before advancing systematically to joint distributions, transformation techniques, and multivariate limit theorems. Each concept is reinforced with clear, written mathematical derivations and practical examples. This course is designed for students preparing for mathematical statistics exams, such as the IIT JAM MS, as well as data analysts seeking a rigorous foundation in probability. No advanced prior knowledge of multivariate calculus is required, as key mathematical tools are introduced sequentially.
