Liniennmodell

Liniennmodell is a term used in German to describe a linear model. A linear model is a statistical model that assumes a linear relationship between the dependent variable and one or more independent variables. This means that the change in the dependent variable is proportional to the change in the independent variables. The simplest form is a simple linear regression, which involves one independent variable. More complex versions, known as multiple linear regression, incorporate several independent variables. The goal of a linear model is often to predict the value of the dependent variable based on the values of the independent variables or to understand the strength and direction of the relationships between them. The coefficients in a linear model quantify the impact of each independent variable on the dependent variable, holding other variables constant. These models are widely used in various fields, including economics, social sciences, and engineering, due to their interpretability and computational efficiency. Assumptions underlying linear models, such as the independence of errors and homoscedasticity, are crucial for valid inference.
