Description

ABOUT THE COURSE:This course is aimed at the students who have already learnt about basic Probability distributions and Random variables, and are interested in learning about the Mathematical formulation of Probability. This is a follow-up of the NPTEL course “Measure Theoretic Probability 1”. Knowledge of measure theoretic integration will be assumed. PG/Ph.D students and senior UG students are welcome. We shall first discuss the various notions of convergence of random variables and and then focus on the Law of Large Numbers and the Central Limit Theorem.INTENDED AUDIENCE: This is a follow-up of the NPTEL course “Measure Theoretic Probability 1”. Target audience includes students who have already learnt about basic Probability distributions and Random variables, and are interested in learning the Mathematical formulation of Probability. Knowledge of measure theoretic integration will be assumed. PG/Ph.D students and senior UG students are welcome.PREREQUISITES: A good background of Real Analysis, Basic Probability Theory (covering Probability distributions and standard Random variables) and Measure Theoretic Integration.INDUSTRY SUPPORT: This is a course focused on the Mathematical foundations of Probability and not on applications. However, this course is useful prerequisite towards advanced courses such as Stochastic Calculus and Financial Mathematics. As such, most industries should recognize this course.
