Regression analysis. In statistics, regression analysis includes any
techniques for modeling and analyzing several variables, when the focus
is on the relationship between a dependent variable and one or more
independent variables. Most commonly, regression analysis estimates the
conditional expectation of the dependent variable given the independent
variables. Therefore, the estimation target is a function of the independent
variables called the regression function. Regression analysis is widely
used for prediction and forecasting, where its use has substantial overlap
with the field of machine learning.
