Sample cases under Hd for sample-dependent error probabilities, $w_t$ and $w_r$

One latent genotype, ZD, for true donor (D) and one latent genotype, ZS, for suspect (S).

Usage

sample_data_Hd_wTwR(n, wT, wR, p, ...)

Arguments

n

number of samples

wT

error probability for donor sample

wR

error probability for PoI sample

p

list of genotype probabilities (length is number of loci) or vector of length 3 for single locus

...

Passed on to add_errors_to_genotypes()

Value

list of two matrices, each of size n x loci with genotype in 0/1/2 format resembling the situation in real life.

Examples

sample_data_Hd_wTwR(n = 10, wT = 0.3, wR = 1e-6, p = c(0.25, 0.25, 0.5))
