BET (version 0.5.4)

symm: Symmetry Statistics for all Interactions

Description

symm returns all the symmetry statistics up to depth d in marginal binary expansions for the tests BET and BETs.

Usage

symm(
  X,
  dep,
  unif.margin = FALSE,
  print.sample.size = TRUE
)

Value

The result is a dataframe with \((p+2)\) columns, where \(p\) is the number of columns of X. The first column gives the binary index for all variables, the next \(p\) columns displays all the interactions of respective variables, the last column of Statistics gives the respective symmetry statistic.

Arguments

X

a matrix to be tested.

dep

depth of the marginal binary expansions.

unif.margin

logicals. If TRUE the data has been uniformed based on empirical cumulative distribution function. Default to be FALSE and the function uniforms the data.

print.sample.size

logicals. If TRUE print the sample size. Default to be TRUE.

Examples

v <- runif(128, -pi, pi)
X1 <- cos(v) + 2.5 * rnorm(128, 0, 1/20)
X2 <- sin(v) + 2.5 * rnorm(128, 0, 1/20)
symm(cbind(X1, X2), 3)
