A.numnorm()

Description:

Normalize a sequence type numeric variable during modeling.

Sytnax:

A.numnorm()

During modeling, normalize numeric variable A and return a binary sequence containing the normalization result and normalization process records Rec

A.numnorm@r(Rec)

During scoring, normalize numeric variable A according to normalization process records Rec

Note:

The external library function (See External Library Guide) normalizes a sequence type numeric variable during modeling.

Parameter:

A

A sequence, which is a numeric variable

Rec

A sequence of normalization process records

Option:

@c

Modify the original data to the normalization result after execution

Return value:

A sequence

Example:

 

A

 

1

[1,2,3,4,5,6,7,8,9,10]

 

2

=A1.numnorm()

A2(1) Normalization result;

A2(2) Normalization process records Rec.

3

=A1.numnorm@rc(A2(2))

Normalize A1’s sequence according to A2’s normalization process records Rec.
