Ordinary least squares regression of Okun's law.Since the regression line does not miss any of the points by very much, the R 2 of the regression is relatively high.. In statistics, the coefficient of determination, denoted R 2 or r 2 and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s).
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.
Because the ® symbol is not commonly available on typewriters (or ASCII), it was common to approximate it with the characters (R) (or (r)). [ a ] [ b ] An example of a legal equivalent is the phrase Registered, U.S. Patent and Trademark Office , which may be abbreviated to Reg U.S. Pat & TM Off.
The set of real numbers, sometimes called "the reals", is traditionally denoted by a bold R, often using blackboard bold, . [ 2 ] [ 3 ] The adjective real , used in the 17th century by René Descartes , distinguishes real numbers from imaginary numbers such as the square roots of −1 .

The Sator square is arranged as a 5 × 5 grid consisting of five 5-letter words, thus totaling 25 characters. It uses 8 different Latin letters: 5 consonants (S, T, R, P, N) and 3 vowels (A, E, O). In some versions, the vertical and horizontal lines of the grid are also drawn, but in many cases, there are no such lines.
R 2 L is given by Cohen: [1] =. This is the most analogous index to the squared multiple correlations in linear regression. [3] It represents the proportional reduction in the deviance wherein the deviance is treated as a measure of variation analogous but not identical to the variance in linear regression analysis. [3]
In Lithuanian, the R with tilde “R̃, r̃” is rarely used and is found in some grammar texts, dictionaries or textbooks. The tilde is used like the circumflex, it indicates the long tonic accent. Therefore, the R with a tilde indicates an /r/ that is part of a diphthong with a tonic accent.
