Glossary
- Adjusted
r2 A measure of the explanatory power of a regression model that takes into consideration the number of independent variables in the model.
- Binary Variable
See Dummy Variable.
- Coefficient of Correlation
(r) A measure of the strength of the relationship between two variables.
- Coefficient of Determination
(r2) The percent of the variability in the dependent variable
(Y) that is explained by the regression equation.- Collinearity
A condition that exists when one independent variable is correlated with another independent variable.
- Dependent Variable
The Y variable in a regression model. This is what is being predicted.
- Dummy Variable
A variable used to represent a qualitative factor or condition. Dummy variables have values of 0 or 1. This is also called a binary variable or an indicator variable.
- Error
The difference between the actual value (Y) and the predicted value
(Yˆ). - Explanatory Variable
The independent variable in a regression equation.
- Independent Variable
The X variable in a regression equation. This is used to help predict the dependent variable. Indicator Variable (Binary Variable) A type of independent variable that is either zero or one to indicate the absence (zero) or presence (one) of some condition or force.
- Least Squares
A reference to the criterion used to select the regression line, to minimize the squared distances between the estimated straight line and the observed values.
- Mean Squared Error (MSE)
An estimate of the error variance.
- Multicollinearity
A condition that exists when one independent variable is correlated with other independent variables.
- Multiple Regression Model
A regression model that has more than one independent variable.
- Observed Significance Level
Another name for p-value.
- p-Value
A probability value that is used when testing a hypothesis. The hypothesis is rejected when this is low.
- Predictor Variable
Another name for explanatory variable.
- Regression Analysis
A forecasting procedure that uses the least-squares approach on one or more independent variables to develop a forecasting model.
- Residual
Another term for error.
- Response Variable
The dependent variable in a regression equation.
- Scatter Diagrams or Scatter Plots
Diagrams of the variable to be forecasted, plotted against another variable, such as time. Also called scatter plots.
- Standard Error of the Estimate
An estimate of the standard deviation of the errors; sometimes called the standard deviation of the regression.
- Stepwise Regression
An automated process to systematically add or delete independent variables from a regression model.
- Sum of Squares Error (SSE)
The total sum of the squared differences between each observation (Y) and the predicted value
(Yˆ). - Sum of Squares Regression (SSR)
The total sum of the squared differences between each predicted value
(Yˆ) and the mean(Y¯¯¯). - Sum of Squares Total (SST)
The total sum of the squared differences between each observation (Y) and the mean
(Y¯¯¯).
