  1. A tutorial for Fuzzy Regression Regression A tutorial for Fuzzy Prediction Jin Hee Yoon Yonsei University, South Korea MAR. 1, 2013

  2. A tutorial for Fuzzy Regression Regression 1. Introduction (Regression) Dependent variable Independent variable (x) Regression is the attempt to explain the variation in a dependent variable using the variation in independent variables. Regression is thus an explanation of causation. If the independent variable(s) sufficiently explain the variation in the dependent variable, the model can be used for prediction.

  3. A tutorial for Fuzzy Regression Simple Linear Regression Regression 1. Introduction (Simple Regression) є Dependent variable (y) Independent variable (x) LSE (Least squares estimation) LAD (Least absolute deviation) ( Estimated regression model)

  4. A tutorial for Fuzzy Regression Multiple Linear Regression Regression 1. Introduction (Multiple Regression) More than one independent variable can be used to explain variance in the dependent variable, as long as they are not linearly related. A multiple regression takes the form: LSE (Least squares estimation) LAD (Least absolute deviation)
