#### Regression is the process by which the relationship between two variables is determined. In linear regression analysis, the dependent variable is thought to be related to the independent variable or variables in a linear way. Regression analysis is the branch of mathematical analysis. This method is the combination of several practical processes for recognizing the level of dependence among variables using statistical data. The information is not enough about the distributions of the variables under consideration. With this fact, you can characterize the regression problem in mathematical statistics. For example, random variable Y.Y. has probability distribution at fixed value XX of the other variable such as;
E(Y | x) = g(x, ß), E(Y | x) = g(x, ß),
set of unknown parameters is ß
Determining function is g(x)
The result of observation lets you determine the value of these parameters.
You can use the process of regression in various apps of statistics. It has two core types that are;
**Predictions** - we use regression analysis to generate predictions.
**Correlation** - It is a model that we gain by regression analysis. It is suitable for some kind of data better than others. With it, you can refine a statistical model to add additional inputs.
