Computational Statistics with MATLAB

Computational Statistics with MATLAB

02 January 2024 | Prof. Nitin Geete
The chapter introduces the concept of computational statistics, emphasizing its focus on leveraging information science to develop new statistical methods. It highlights the practicality of these methods due to advancements in computer hardware, which have enabled the storage and processing of large datasets. The traditional approach to data collection and analysis is contrasted with the modern approach, where data is often collected before the study design, leading to highly dimensional and large datasets that traditional statistical tools may struggle with. The chapter also provides an overview of MATLAB, a technical computing environment created by Math Works, Inc., and its basic data structures and programming features. It includes a brief guide on building arrays and calculating descriptive statistics using MATLAB functions. The chapter concludes with a reference to a solution for solving singular and semidefinite linear systems by iteration.The chapter introduces the concept of computational statistics, emphasizing its focus on leveraging information science to develop new statistical methods.
