MeanMin: Data splitting-based two-stage minimum mean testing method for the mean vector.

Description

Conduct the simultaneous inference for a set of mean components in the the Null hypothesises H02 that assumes the set of mean components exist zero.

Usage

MeanMin(X, test.set, Nsplit = 5, frac.size=0.5, standardized=FALSE, alpha=0.05, seed=1)

Value

return a vector with names 'CriticalValue', 'TestStatistic', 'reject_status', 'p-value' if Nsplit=1, and 'reject_status' and 'adjusted_p-value' if Nsplit>1.

Arguments

X

a n-by-p matrix, the observed data

test.set

a positive vector with values between 1 and p, the set of H02.

Nsplit

a positive integer, the random split times used, default as 5.

frac.size

a positive number between 0 and 1, the proportion of the sample used in stage I.

standardized

a logical value, whether standerdize in stage I.

alpha

a positive number, the significant level.

seed

a non-negative integer, the random seed.

Examples

  ### Example
  n <- 100; p <- 100; i <- 1
  s0 <- 5 # First five components are nonzeros
  rho <- 4; tau <- 1;
  dat1 <- gendata_Mean(n, p, s0, seed=i, rho, tau)
  # ex1: H01 is false
  MeanMin(dat1$X, 1:s0)
  MeanMin(dat1$X, 1:s0, Nsplit=1)
  # ex1: H01 is true
  MeanMin(dat1$X, 1:p)
  MeanMin(dat1$X, 1:p, Nsplit=1)
