In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships between a dependent variable (often called the 'outcome' or 'response' variable, or a 'label' in machine learning parlance) and one or more independent variables (often called 'predictors', … See more The earliest form of regression was the method of least squares, which was published by Legendre in 1805, and by Gauss in 1809. Legendre and Gauss both applied the method to the problem of determining, from … See more In linear regression, the model specification is that the dependent variable, $${\displaystyle y_{i}}$$ is a linear combination of the parameters (but need not be linear in the independent variables). For example, in simple linear regression for modeling See more Regression models predict a value of the Y variable given known values of the X variables. Prediction within the range of values in the dataset used for model-fitting is known informally as See more In practice, researchers first select a model they would like to estimate and then use their chosen method (e.g., ordinary least squares) … See more By itself, a regression is simply a calculation using the data. In order to interpret the output of regression as a meaningful … See more When the model function is not linear in the parameters, the sum of squares must be minimized by an iterative procedure. This introduces many complications which are summarized in Differences between linear and non-linear least squares.
