What type of variable is often the focus of a regression analysis?

In regression analysis, the focus is on the target feature, also known as the dependent variable. This type of variable is what the analysis aims to predict or explain based on the influence of other variables. The target feature is central to regression because the whole purpose of the analysis is to understand how changes in one or more independent variables can affect this outcome.

Independent variables are also important, as they are used to predict the target feature, but they are not the primary focus of the analysis. Control variables can be included to account for potential confounding factors, while instrumental variables are used in specific situations to handle issues of endogeneity and are less commonly the focus in standard regression analyses.
