Description:
Correct skewness of a sequence of numeric target variables.
Syntax:
A.tarcorskew() |
During the modelling process, correct skewness of a sequence A of numeric target variables, handle outliers, and return the result sequence of outcomes and the sequence of correction and handling records, represented by Rec |
A.tarcorskew@r(Rec) |
Get the restored values of score values according to Rec, the sequence of correction and handling records after model scoring |
Note:
The external library (See External Library Guide) corrects skewness of a sequence of numeric target variables.
Parameter:
A |
A sequence of numeric target variables |
Rec |
The sequence of correction and handling records |
Option:
@c |
Modify the original data to the corrected values after execution |
Return value:
Sequence
Example:
|
A |
|
1 |
=T("D://house_prices_train.csv") |
|
2 |
=A1.(SalePrice) |
A sequence of numeric target variables. |
3 |
=A2.skew() |
The skewness of original data. |
4 |
=A2.tarcorskew@c() |
Return the result of skewness correction and skewness correction records and modify the original data. |
5 |
=A2.skew() |
The corrected skewness. |
6 |
=A2.tarcorskew@r(A4(2)) |
Recover the corrected data to their original values according to skewness correction records, usually in order to restore the score values. |
