1/15뒤로Skip to main content뒤로Multiple Regression
A statistical method analyzing how several independent variables collectively influence a single dependent variable. Independent Variable
A factor in a regression model used to predict or explain changes in the dependent variable. Dependent Variable
The outcome or response in a regression model influenced by one or more independent variables. Coefficient
A numerical value in a regression equation representing the effect size of an independent variable. Y Intercept
The constant term in a regression equation indicating the predicted value when all predictors are zero. R Squared
A measure showing the proportion of variation in the dependent variable explained by the model's predictors. Adjusted R Squared
A refined metric that accounts for the number of predictors, penalizing irrelevant variables to improve model quality. Irrelevant Variable
A predictor that lacks a logical or predictive relationship with the dependent variable, reducing model effectiveness. Relevant Variable
A predictor with a clear, logical, and predictive connection to the dependent variable, enhancing model accuracy. Data Analysis Toolpak
An Excel add-in providing tools for statistical analysis, including regression modeling and output generation. Overfitting
A modeling issue where too many predictors cause the model to fit noise rather than meaningful patterns. Predictive Relationship
A logical connection where changes in one variable can be used to anticipate changes in another. Double Dipping
Including multiple predictors that provide overlapping information, leading to redundancy in the model. Coefficient of Determination
Another term for R squared, indicating the explanatory power of the regression model. Regression Equation
A mathematical formula expressing the relationship between the dependent variable and its predictors.
