The distance square in the Newton's law of universal gravitation is really a square? (7 answers) Closed 9 years ago. Is there something intrinsic about the structure of space that gravity is proportional to 1/r^2 instead of, for example, 1/r^2.143 ? What makes the exponent turn out to be a nice even number? newtonian-gravity Share Cite

Massless photon case: Now, the 1 / r potential gives rise to a force that goes as 1 / r 2. This force decreases as the area of the sphere of radius r, indicating that the force 1 / r 2 is a purely geometrical fact of 3 spatial dimensions: intuitively, we emit N photons from a point and the force decreases with the surface density of the photons.

The " coefficient of determination " or " R-squared value ," denoted R 2, is the regression sum of squares divided by the total sum of squares. Alternatively (as demonstrated in the video below), since SSTO = SSR + SSE, the quantity R 2 also equals one minus the ratio of the error sum of squares to the total sum of squares:

You can find the gradient of $1/r$ more easily using the chain rule and the identity $\nabla r^2 = 2 \vec r$. In particular, $$\nabla \frac{1}{r} = \nabla \frac{1}{\sqrt{r^2}} =- \frac{1}{2 (r^2)^{3/2}} \nabla r^2 =-\frac{\vec r}{ r^3} = -\frac{\hat r}{r^2}$$ Finally, in evaluating the problem $\nabla \cdot \hat r$, you can use the product rule:

Published on April 22, 2022 by Shaun Turney . Revised on June 22, 2023. The coefficient of determination is a number between 0 and 1 that measures how well a statistical model predicts an outcome. The coefficient of determination is often written as R2, which is pronounced as "r squared."

(y1-y_bar)^2 + (y2-y_bar)^2 + (y3-y_bar)^2 = (1-2)^2 + (2-2)^2 + (3-2)^2 = 2. this is going to be a very small fraction over here. 1 minus a very small fraction is going to be a number close to 1. So then, our R-squared will be close to 1, which tells us that a lot of the variation in y is described by the variation in x. Which makes sense.

The coefficient of determination or R squared method is the proportion of the variance in the dependent variable that is predicted from the independent variable. It indicates the level of variation in the given data set. The coefficient of determination is the square of the correlation (r), thus it ranges from 0 to 1.
