In statistics, r value correlation means correlation coefficient, which is the statistical measure of the strength of a linear relationship between two variables.If that sounds complicated, don't worry — it really isn't, and I will explain it farther down in this article. But before we get into r values, there's some background information you should …

Definition 4.1.1 THe Position Vector. Let P = (p1, ⋯, pn) be the coordinates of a point in Rn. Then the vector → 0P with its tail at 0 = (0, ⋯, 0) and its tip at P is called the position vector of the point P. We write → 0P = [p1 ⋮ pn] For this reason we may write both P = (p1, ⋯, pn) ∈ Rn and → 0P = [p1⋯pn]T ∈ Rn.Mathematical Annotation in R argument to one of the text-drawing functions (, mtext, axis , ) in R is an expression, the argument is interpreted as a mathematical expression and the output will be formatted according to TeX-like rules.

The formula for the nth term of a geometric progression whose first term is a and common ratio is r is: a n =ar n-1. The sum of n terms in GP whose first term is a and the common ratio is r can be calculated using the formula: S n = [a (1-r n )] / (1-r). The sum of infinite GP formula is given as: S n = a/ (1-r) where |r|<1.

20. Formulas. Many commands in R are specified in terms of formulas. A formula has a tilde ( ~ ), left-hand side terms and right-hand side terms. y ~ x. The terms are composed of data object names or expressions. These are usually variables in a data frame, but they can also include matrices, or the results of embedded expressions like log (x).In mathematics, the alphabet R denotes the set of real numbers.

This imposing explicit formula for the number of ways to tile an m×n rectangle with 2×1 dominos. This strange looking identity that relates π to the expected value of a random infinite nested radical.A Midrange of a given function can be calculated with the help of the following steps:-. Step 1: First, we need to find what is the maximum value in the data set. Maximum Value in the data set is calculated as. Step 2: Then we need to find what is the minimum value in the data set.Example 1: In a GP, the sum of the first three terms is 16, and the sum of the next three terms is 128. Find the sum of the first n terms of the GP. Solution: Let 'a' and 'r' be the first term and the common ratio of the given GP respectively. Then: a + ar + ar 2 = 16. ar 3 + ar 4 + ar 5 = 128.
