Linear Regression Analysis: Some Basic Concepts, definition, simple vs. multiple model and linearity

Описание: Linear Regression Analysis: Some Basic Concepts

In this video, we explore the fundamental concepts of linear regression analysis, a key statistical technique used to model relationships between variables. We start by explaining the meaning of regression analysis, which helps us understand how one or more independent variables influence a dependent variable.

Next, we differentiate between the simple regression model (which involves only one independent variable) and the multiple regression model (which includes two or more independent variables). Understanding this distinction is crucial for applying regression analysis in real-world scenarios.

Finally, we clarify the meaning of the term linear in regression analysis. A regression model is considered linear if the relationship between the dependent and independent variables can be expressed as a linear equation. This does not necessarily mean the variables themselves are linear, but rather that the model parameters appear in a linear form.
