• The Pythagorean theorem says that the square on the hypotenuse of a right triangle is equal in area to the sum of the squares on the legs.• The Squared Euclidean distance (SED) is defined as the sum of squares of the differences between coordinates.• Heron's formula for the area of a triangle can be re-written as using the sums of squares of a triangle's sides (and the sums of the squares of squares)

15.05.2020 · The sum of squares got its name because it is calculated by finding the sum of the squared differences. This image is only for illustrative purposes. The sum of squares is one of the most important outputs in regression analysis. The general rule is that a smaller sum of squares indicates a better model, as there is less variation in the data.

What is Sum of Squares? Sum of squares (SS) is a statistical tool that is used to identify the dispersion of data as well as how well the data can fit the model in regression analysis Regression Analysis Regression analysis is a set of statistical methods used to estimate relationships between a dependent variable and one or more independent variables..

Efficient approach. The key insight is that both sum of squares and square of sum follow a pattern and is captured by a mathematical equation. On finding the equation, we can find the respective values instantly and take the difference. The equations are: Sum of 1 to N = N * (N+1) / 2. Sum of square of 1 to N = (2 * N + 1) * (N + 1) / 6.
