Definitions:

Error SSE

The sum of squared errors (SSE) is a measure used in statistics to quantify the discrepancy between the data and an estimation model.

Coefficient of Determination

A statistical measure that expresses the proportion of variance in the dependent variable that can be predicted from the independent variable(s).

Standard Error

A measure of the dispersion or variance of sample means around the population mean.

Regression Line

A regression line is a straight line that best fits the data points in a scatter plot, showing the relationship between an independent and a dependent variable.
