Attributes
Build a rectangular tensor from the var-argument list x.
Build a rectangular tensor from the var-argument list x.
Value parameters
- n
-
the four dimensions (n1, n2, n3, n4)
- x
-
the values for the tensor
Attributes
Count the joint frequency of occurrence of value triple (x_ij, x_ip, y_i) for each column j in the data matrix. Value counts for each column determine dim2, value count for parent p gives dim2, while the value count for y gives dim4.
Count the joint frequency of occurrence of value triple (x_ij, x_ip, y_i) for each column j in the data matrix. Value counts for each column determine dim2, value count for parent p gives dim2, while the value count for y gives dim4.
Value parameters

-
the third dimension of the resulting tensor (# values for y)
- pa
-
the parent vector giving xp for each xj
- x
