BinaryAssociation

BinaryAssociation produces a data.framed matrix of association measures between binary variables.

BinaryAssociation(X, Y = NULL, TYPE = "YuleQ", DIGITS = 3,
  ASMATRIX = F)

Arguments

X

either a binary variable or a data.frame containing binary variables (non binaries are discarted)
Y

=NULL only used of X is a binary variable
TYPE

="YuleQ". Choose association measure among c("OddsRatio", "logOddsRatio", "YuleY", "YuleQ", "RR")
DIGITS

=3 Number of digits of association measures
ASMATRIX

= F if TRUE returned result is a KxK matrix not a data.frame with rownames as first column (default)

Value

a data.frame with colnames[1] indicating the TYPE or matrix if ASMATRIX = T)

Examples

if (FALSE) {
require(MASS)
BinaryAssociation(birthwt)
Table(birthwt$smoke,birthwt$low)
BinaryAssociation(birthwt$smoke,birthwt$low)
BinaryAssociation(birthwt$smoke,birthwt$low,TYPE="logOddsRatio")
}
