Hypergeometric p-value and Distribution Overlaid with Normal Distribution

Usage

iscamhypernorm(k, total, succ, n, lower.tail, verbose = TRUE)

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)
verbose: Logical, defaults to TRUE. Set to FALSE to suppress messages

Value

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

Examples

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

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