Linear regression can produce curved lines and nonlinear regression is not named for its curved lines So when should you use Nonlinear Regression over one of our linear methods such as Regression Best Subsets or Stepwise Oct 21 2024 nbsp 0183 32 The Regression Equation When regression is used the regression line is being used to estimate scores of the Y Y variable Thus the equation of the line is the formula used
However the actual reason that it s called linear regression is technical and has enough subtlety that it often causes confusion For example the graph below is linear regression too even though the resulting line is curved The definition The goal of linear regression is to find the best fitting line or curve that describes how the dependent variable changes as a function of the independent variables Dependent and Independent Variables
