contr <- rep(c(1/sum(n[2]), -1/sum(n[1])), n[2:1])


B <- 100
T <- array(0, dim = c((B + 1), p))

g <- monachus[, 1]
data <- monachus[, -1]

T[1, ] <- t(data) %*% contr

for (bb in 2:(B + 1)) {
    data.star <- data[sample(1:sum(n)), ]
    T[bb, ] <- t(data.star) %*% contr
}

P <- t2p_old(abs(T))
colnames(P) <- colnames(data)
cat("Rough p-values \n")
t(t(P[1, ]))
