What Is Regression In Mathematics. Jun 06 2020 A branch of mathematical statistics that unifies various practical methods for investigating dependence between variables using statistical data see Regression. It is a linear model that establishes the relationship between a dependent variable y Target and one or more independent variables denoted X Inputs.
May 06 2020 Regression is a type of supervised machine learning problem under which the relationship between features in the data-space and the outcome is established to predict the values for the outcome which are continuous by nature. It is a linear model that establishes the relationship between a dependent variable y Target and one or more independent variables denoted X Inputs. As we know from the basic maths that if we plot an XY graph a linear relationship will always come up with a straight line.
Multiple regression models thus describe how a single response variable Y depends linearly on a number of predictor variables.
Of course the points might not fit the function exactly but the aim is to get as close as possible. The term regression is sometimes also used to refer to recursion. Regression is the supervised machine learning and statistical method and an integral section of predictive models. We can also use that line to make predictions in the data.
