LINEAR MODELS Meaning and
Definition
-
Linear models refer to a type of mathematical and statistical modeling technique used to represent the relationship between a dependent variable and one or more independent variables. It assumes a linear or straight-line relationship between the variables, and therefore, provides a simplified way to understand and predict the behavior of a system or phenomenon.
In a linear model, the dependent variable is considered as a function of the independent variables, where the relationship is represented as a linear equation. This equation is expressed in the form of Y = β0 + β1X1 + β2X2 + ... + βnXn, where Y represents the dependent variable, X represents the independent variables, β0 represents the intercept, and β1, β2, ..., βn represent the coefficients of the independent variables.
The goal of linear modeling is to estimate the values of these coefficients through a process called estimation or regression analysis, which involves minimizing the difference between the observed and predicted values of the dependent variable. This estimation is typically done through various techniques such as ordinary least squares, maximum likelihood estimation, or other optimization algorithms.
Linear models are widely used in various fields such as economics, finance, social sciences, engineering, and more. They provide a simple and interpretable way to analyze and quantify the relationship between variables, make predictions, and understand the impacts of the independent variables on the dependent variable. However, it is important to note that linear models assume a linear relationship and may not be appropriate for data with complex or nonlinear patterns.

Etymology of LINEAR MODELS
The etymology of the term "linear models" can be traced back to the Latin word "linearis", which means "belonging to a line". In mathematics, the concept of a line is represented by a linear equation, which is an equation describing a straight line. The term "linear models" refers to statistical models that assume a linear relationship between the independent and dependent variables. It relates to the use of linear equations to represent the relationship between variables in statistical modeling.
