Probability
Functions
Probability functions are often used in statistical analyses.
COMB
Number of combinations (without regard to order) of n things
taken rat a time, n!/(r!(n-r)).
COMB (n,r)
!
Factorial of a positive integer. For non-integers, ! = F(x + 1).
value !
PERM
Number of permutations (with regard to order) of n things
taken rat a time, n\/ (_n-r)\.
PERM(n,r)
RANDOM
Random number (between zero and 1). Produced by a pseudo
random number sequence. Becomes the seed for the next
random number.You can set the seed using the command
RANDSEED.
RANDOM
UTPC
Upper-Tail Chi-Squared Probability given degrees of freedom,
evaluated at value. Returns the probablility that a random
variable is greater than value.
UTPC ( degrees, value )
UTPF
Upper-Tail Snedecor’s F Probability given numerator degrees of
freedom and denominator degrees of freedom (of the F
distribution), evaluated at value. Returns the probability that a
Snedecor's F random variable is greater than value.
UTPF {numerator, denominator, value)
UTPN
Upper-Tail Normal Probability given mean and variance,
evaluated at value. Returns the probability that a normal
random variable is greater than value for a normal distribution.
(The variance is the square of the standard deviation.)
UTPN ( mean, variance, value )
UTPT Upper-Tail Student's t Probability given degrees of freedom,
evaluated at value. Returns the probability that the Student's t
random variable is greater than value.
UTPT ( degrees, value )
