Command Syntax

Lower value, Upper value, n:df value, d:df value

Definition of Terms

Lower : lower boundary

Upper : upper boundary

n:df : degrees of freedom of numerator (positive integer)

d:df : degrees of freedom of denominator (positive integer)

Input Example:

FCD 0.76,3,2,3

Calculation Result Output

p : F distribution probability

kBinomial Distribution

Binomial Probability

Command: BinomialPD ￿

Description: This command calculates the probability that a random variable that follows a binomial distribution will be a given x value. For example, it determines the probability of x successes when the probability of success p-trial is performed

ntimes.

f (x) = n C x px (1–p)n– x

(x = 0, 1, ·······, n)

p : probability of success

 

 

(0 <p <1)

 

 

n : number of trials
