Arguments

data	A data frame
var.x	The regressor (or predictor) variable (has to be the name of a variable in data)

x.value	(optional) The value of var.x to condition upon (has to be a value of data[[var.x]])

Value

• If x.value is specified, returns PRI(var.y|var.x = x.value) = 1 - H(var.y|var.x = x.value)/H(var.y).

• If x.value is not specified, returns RI(var.y|var.x) = MI(var.x,var.y)/H(var.y)
