Regression analysis

Definition

Regression analysis is a statistical method used to determine the relationship between a dependent variable and one or more independent variables. This technique helps identify how changes in the independent variables can impact the dependent variable, which is crucial for making informed decisions in various fields, including business and problem-solving contexts. By analyzing this relationship, individuals can predict outcomes and understand the strength and nature of these connections.
