Usage

nd2bn(bn, ion)

Arguments

bn	The original bn.
ion	The definition of the target node.

Details

The two limits used for the uniform distribution of the parents are taken from their @lpod or @lred attributes. If these limits are not convenient, they can easily being modified with mnd4bn function afterwards. When there are more than one parent, the uniform are independent. See also uniform4bn for the description of uniform in case of multivariate and repeated nodes.

Value

The resulting bn.

Examples

 rebastaba3k("RESET"); # (only for R checking)
