symm: Symmetry Statistics for all Interactions

In BET: Binary Expansion Testing

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
)

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.

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.

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)
