Least Squares Estimate

A statistical technique that determines the line of best fit for a model by minimizing the sum of the squares of the vertical differences (residuals) between the observed values and the values predicted by the model.

Intercept

In the context of mathematical graphs and equations, it refers to the point where a line or curve crosses an axis.
