In a regression model, the causal relationship between variables X and Y allows an analyst to accurately predict the Y value for each X value. In simple regression, there is only one independent variable X, and the dependent variable Y can be satisfactorily approximated by a linear function. Summary Definition. Define Regression Modeling: Regression model means an investment analysis tool used by investors to compare two or more stock variables.
The independent variable is independent because its variation does not depend on the variation of another variable in the experiment/research project. The independent variable is controlled or changed only by the researcher. This factor is often the research question/hypothesis behind the outcome of the experiment. In the above example, the researcher may have wanted to see if participating in the training program raised students' scores on a final test.
