Regression, regression - are these words related by value? Yes, of course, connected. These are single-root words, derived from the Latin root regressus, meaning "backward movement." Only the meanings of the word “regression” are already several.

Let's understand in more detail what is regression.

## The meaning of the word "regression"

- In psychology, regression is called the defense mechanism of a person, his psyche, when a person finds himself in such a difficult situation that he begins to behave as he would never lead normally. For example, a child who commits an offense often begins to pretend that he is ill, so that he can be forgiven and pityed.
- Regression is also the process of the retreat of the sea when shifts occur in the earth's crust. For example, scientists annually record the Black Sea regression.
- Regression is a mathematical, technical term. It indicates the relationship between variables, which allows you to predict the future behavior of these variables. For example, regression can be represented as a simple equation that shows the relationship between two groups of numeric variables.
