Introduction

We are comparing our method with ASH and SVA.

library(ashr)
library(edgeR)
library(limma)
library(seqgendiff)
library(sva)
library(pROC)
source("../code/gdash.R")

Artefactual effects \(\pi_0\delta_0 + \left(1 - \pi_0\right)N\left(0, \sigma^2\right)\) are added to the real GTEx data.

mat = read.csv("../data/liver.csv")

The setting: \(\pi_0 = 0.5\), \(\sigma^2 = 9\)

N = 200
nsamp = 10
ngene = 1e4
pi0 = 0.5
sd = 3
set.seed(777)
system.time(gdash.comp <- N_simulations(N, mat, nsamp, ngene, pi0, sd))
