split-sample: Split Sample for Binomial Data

In Rariant: Identification and Assessment of Single Nucleotide Variants through Shifts in Non-Consensus Base Call Frequencies

Description

Sample splitting, according to Hall, 2014.

Usage

splitSampleBinom(x, n)

Arguments

x	Number of successes
n	Number of trials

Details

These functions implement sample splitting of a binomial rate.

Note that the results depend on the state of the random number generator, and are therefore not strictly deterministic.

Value

A vector with the rate p = X/N, obtained with sample splitting.

Examples

n = 10
m = 5
pt = 0.5

x = rbinom(m, n, pt)
p = x/n

ps = splitSampleBinom(x, n)

round(cbind(p, ps), 2)
