REGRESSION ANALYSES Meaning and
Definition
-
Regression analysis is a statistical method used to examine the relationship between a dependent variable and one or more independent variables. It is commonly used in various fields such as economics, psychology, and social sciences to understand the impact of independent variables on the dependent variable and to make predictions or forecasts.
In regression analysis, the dependent variable, also known as the outcome or response variable, is the variable that is being predicted or explained. This variable is usually a continuous quantity, such as income, sales, or test scores. The independent variables, also called predictors or explanatory variables, are the variables that are believed to influence or explain the changes in the dependent variable. These variables can be continuous or categorical, such as age, gender, or education level.
Regression analysis aims to estimate the relationship between the dependent variable and the independent variables by fitting a mathematical model to the observed data. The most common type of regression analysis is linear regression, where a straight line is used to represent the relationship between the variables. However, there are also other types of regression analyses, such as logistic regression for binary outcomes or polynomial regression for non-linear relationships.
The output of a regression analysis includes the estimated coefficients for each independent variable, which indicate the magnitude and direction of the relationship, as well as statistical measures to assess the goodness of fit and the significance of the model. Regression analysis helps in identifying which independent variables are significant predictors of the dependent variable and how they contribute to its variation.

Etymology of REGRESSION ANALYSES
The word "regression" in the context of statistical analysis comes from the Latin word "regressus", which means "returning" or "going back". It was first used in the late 19th century in the field of genetics by British scientist Francis Galton. Galton used the term to describe a statistical phenomenon related to hereditary traits.
The term "analysis" comes from the Greek word "analyein", meaning "to dissolve" or "to break down". It refers to the process of examining something closely and breaking it down into its constituent parts.
When these two terms are combined, "regression analysis" refers to the statistical technique of modeling the relationship between a dependent variable and one or more independent variables. It involves analyzing and quantifying the relationship between variables and making predictions based on the observed data.
