rCorrelation coefficient.
x | Uses a and b to calculate predicted x value |
| when you input a y value. |
y | Uses a and b to calculate predicted y value |
| when you input an x value. |
Probability
nPr | Calculates the number of possible permutations |
| of n items taken r at a time, given n and r. The |
| order of objects is important, as in a race. |
|
|
nCr | Calculates the number of possible combinations |
| of n items taken r at a time, given n and r. The |
| order of objects is not important, as in a hand |
| of cards. |
!A factorial is the product of the positive integers from 1 to n. n must be a positive whole number 69.
RAND | Generates a random real number between |
| 0 and 1. To control a sequence of random |
| numbers, store an integer (seed value) 0 |
| to rand. The seed value changes randomly |
| every time a random number is generated. |
|
|
RANDI | Generates a random integer between 2 |
| integers, A and B, where A RANDI B. |
| Separate the 2 integers with a comma. |
