The goal of this book is not to teach econometrics from scratch, as I assume the reader already has foundational knowledge in the field. Instead, it aims to provide a clear, step-by-step guide to implementing major statistical analyses commonly used in time series analysis. Many students, even after completing advanced coursework in econometrics and statistics, struggle with the practical application of these essential tests. Traditional econometrics materials are often filled with complex mathematical jargon and offer limited guidance on applying these tests using EViews software.
