Accelerating the pace of engineering and science

An Introduction to Dataset Arrays

Michael Weidman, MathWorks

Mixed data (a combination of data types such as numbers, text, dates, categories, etc.) can be painful to organize and analyze. Whether it is “panel data” in finance, “experimental results” in the sciences, or the like, it has traditionally required the use of either multiple variables or generic data containers during analysis. The Dataset array in MATLAB’s Statistics and Machine Learning Toolbox offers a superior solution: a single, easy-to-use object that can import, analyze, and export the (possibly) mixed data.

In this webinar we use a case study of unbalanced panel data to highlight a typical workflow for and the features of Dataset arrays. We discuss features such as categorical arrays, name-based indexing, and joining datasets.
