External library function (See YModel User Reference).
The function performs data prediction and returns prediction result object.
Parameter:
|
pcfObj |
pcf object. |
|
data |
Data used for prediction, which can a .mtx/.csv file, a table sequence or a cursor. |
Return value:
Prediction result object
Example:
|
