Definitions:

Coefficient Of Correlation

A statistical measure that quantifies the degree to which two variables change together; ranging from -1 to 1.

Least Squares Estimate

A method in regression analysis to estimate the coefficients by minimizing the sum of the squared residuals.

Population Slope

It refers to the slope of the line that best fits the entire population data in a regression model, representing the average change in the dependent variable for a one-unit change in the independent variable.

Sum Of Squared Residuals

The total value obtained by squaring each of the residuals (differences between observed and predicted values) and summing them all, commonly used in regression analysis.
