check.ordered.to.pa {bnpa}

Verifies if there are ordered factor variables to be declared in the pa model building process

Description

Receives a BN structure and a data set, then verifies if there are ordered variables. In a positive case return TRUE.

Usage

check.ordered.to.pa(bn.structure, data.to.work)

Arguments

bn.structure

is a BN structure learned from data used to identify if the variable is endogenous or exogenous when building the PA model.

data.to.work

is a data set containing the variables of the BN.

Value

a data frame with ordered variables.
