Mathematical Statistics Notes for BS/MSc

Mathematical Statistics is a branch of mathematics that deals with the study of statistical concepts, models, and methods using mathematical principles. It provides a rigorous foundation in various fields, including engineering, science, social sciences and economics.

Mathematical statistics is a branch of mathematics that deals with the theoretical aspects of statistical methods and the mathematical foundations underlying statistical reasoning and inference. It provides a framework for understanding and developing statistical techniques, making it an essential part of the broader field of statistics.

#### Key topics and concepts in mathematical statistics include:

**Probability Theory:**Mathematical statistics often begins with a solid foundation in probability theory. Probability concepts, such as random variables, probability distributions, and expectations, are fundamental to understanding statistical methods.**Statistical Inference:**This involves drawing conclusions about a population based on a sample of data. Key components of statistical inference include estimation and hypothesis testing.**Estimation:**Involves estimating unknown parameters of a population based on sample data. Methods include interval estimation and point estimation.**Hypothesis Testing:**Involves making decisions or inferences about a population based on sample data. It includes concepts like null and alternative hypotheses, significance levels, and p-values.

**Sampling Theory:**Addresses the selection of samples from populations and the properties of various sampling methods. It includes concepts such as random sampling, sampling distributions, and the Central Limit Theorem.**Bayesian Statistics:**This branch of mathematical statistics involves using Bayesian methods, which incorporate prior knowledge and beliefs to update probability distributions based on observed data.**Nonparametric Statistics:**Focuses on statistical methods that do not rely on specific assumptions about the underlying population distribution. It includes rank-based tests and distribution-free methods.**Time Series Analysis:**Deals with analyzing and modeling data collected over time. It includes methods for trend analysis, seasonality, and forecasting.

Mathematical statistics provides the theoretical underpinning for the methods and techniques used in applied statistics, which is concerned with practical applications in various fields such as economics, biology, engineering, and social sciences. Understanding the mathematical foundations is crucial for developing sound statistical methods, assessing their properties, and making valid statistical inferences.
