Visualize Hypergeometric Distribution

Share:

Description

Generates a plot of the Hypergeometric distribution with user specified parameters.

Usage

1
visualize.hyper(stat = 1, m = 5, n = 4, k = 2, section = "lower", strict = FALSE)

Arguments

stat

a statistic to obtain the probability from. When using the "bounded" condition, you must supply the parameter as stat = c(lower_bound, upper_bound). Otherwise, a simple stat = desired_point will suffice.

m

m white balls. m must be greater than 0.

n

n black balls. n must be greater than 0.

k

draw k balls without replacement.

section

Select how you want the statistic(s) evaluated via section= either "lower","bounded", "upper", or"tails".

strict

Determines whether the probability will be generated as a strict (<, >) or equal to (<=, >=) inequality. strict= requires either values = 0 or =FALSE for equal to OR values =1 or =TRUE for strict. For bounded condition use: strict=c(0,1) or strict=c(FALSE,TRUE).
