WebQuestion: Problem 2: The Method of Least Squares (also known as line of best fit/linear regression)Part I: The method of least squares is used extensively in physics and engineering experiments where measurements of n-pairs (𝑥𝑖 , 𝑦𝑖 ) of two physical quantities are observed. If the relationship between these two quantities is known ... WebIn simple linear regression, both the response and the predictor are continuous. In ANOVA, the response is continuous, but the predictor, or factor, is nominal. The results are related statistically. In both cases, we’re building a general linear model. But the goals of …
