What does it mean to regress something on something else?

What does it mean to regress something on something else?

(transitive, statistics) To perform a regression on an explanatory variable. When we regress Y on X, we use the values of variable X to predict those of Y.

What does it mean to run a regression on something?

Regression analysis is a reliable method of identifying which variables have impact on a topic of interest. The process of performing a regression allows you to confidently determine which factors matter most, which factors can be ignored, and how these factors influence each other.

How do you regress something?

Many times we need to regress a variable (say Y) on another variable (say X). In Regression, it can therefore be written as Y=a+bX; regress Y on X: regress true breeding value on genomic breeding value, etc.

What does it mean to regress a variable in regression?

In Regression, it can therefore be written as Y = a + b X; regress Y on X: regress true breeding value on genomic breeding value, etc. Thanks for contributing an answer to Cross Validated!

What do you call a regression with more than one x variable?

In multiple regression, the linear part has more than one X variable associated with it. When we run a multiple regression, we can compute the proportion of variance due to the regression (the set of independent variables considered together). This proportion is called R-square.

What does it mean to regress y against X?

When we say, to regress Y against X, do we mean that X is the independent variable and Y the dependent variable? i.e. Y = a X + b. It typically means finding a surface parametrised by known X such that Y typically lies close to that surface. This gives you a recipe for finding unknown Y when you know X. As an example, the data is X = 1,…,100.

Why do we use the word regressed instead of dependent?

The word “regressed” is used instead of “dependent” because we want to emphasise that we are using a regression technique to represent this dependency between x and y. Every predicted y shall “be dependent on” a value of x through a regression technique.
