Hypergeometric p-value and Distribution Overlaid with Normal Distribution

Hypergeometric p-value and Distribution Overlaid with Normal Distribution

Usage

hypernorm(k, total, succ, n, lower.tail)

Arguments

k

Number of successes of interest or difference in conditional proportions

total

Total number of observations in the study

succ

Overall number of successes

n

Number of observations in group A

lower.tail

Boolean for finding the probability above (FALSE) or below (TRUE) the inputted value (inclusive)

Value

Tail probabilities from the hypergeometric distribution, hypergeometric distribution with normal distribution overlayed with the observed statistic and more extreme shaded.

Examples

hypernorm(1, 20, 5, 10, TRUE)

#>  hypergeometric: 0.1517 
#>  normal approx: 0.06553 
#>  normal approx with continuity: 0.1571
