How To Detect Heteroskedasticity? In this informative video, we will cover the important topic of heteroskedasticity in regression analysis. Understanding this concept is essential for anyone working with statistical models, especially in fields like economics and data science. We will discuss how to identify heteroskedasticity through both informal and formal methods. Informal methods include visually inspecting residual plots, which can reveal patterns indicating the presence of varying error variances. On the other hand, formal methods involve specific statistical tests such as the Breusch-Pagan Test, the White Test, and the Goldfeld-Quandt Test. Each of these tests has its own approach to detecting heteroskedasticity and can provide further clarity on the reliability of your regression results.

Additionally, we will touch on the implications of ignoring heteroskedasticity and how it can impact your model’s performance. If you do encounter this issue, we will also provide some techniques to correct it, ensuring that your data analysis remains robust. Whether you're a student, researcher, or professional, this video will equip you with the knowledge you need to handle heteroskedasticity effectively.
