Description:
Present the prediction result.
Syntax:
|
ym2_result(preObj) |
Display the prediction result |
|
ym2_result@s(mcfObj, varname) |
Return result of aggregation on a certain field of the mcf object |
Note:
External library function (See YModel User Reference).
The function presents the prediction result and returns a table sequence.
Parameter:
|
preObj |
Prediction result object / pcf object |
|
mcfObj |
mcf object |
|
varname |
Field name |
Option:
|
@p |
Return model performance information |
|
@r |
Return model display information |
|
@i |
Return the degree of importance |
|
@s |
Return information of aggregation on a field |
|
@j |
Return a JSON string; the option works with another option, such as @ij, but it does not work with @s option |
Return value:
Table sequence
