Definitions:

Estimated Value

A value determined through approximation or inference based on statistical models, often used when exact data is unavailable.

Partial Regression Coefficient

A measure that represents the change in the dependent variable for a one-unit change in the predictor variable, holding all other predictors constant.

Coefficient of Determination

A statistical measure, often denoted as \(R^2\), that represents the proportion of the variance in the dependent variable that is predictable from the independent variables.

Dependent Variables

In statistics and experiment design, these are the variables being tested and measured, expected to change as a result of manipulations to the independent variables.
