DM_setFldOutlLim

This method sets outlier limits for the specified field contained in a DM_LogicalDataSpec value. All values that fall outside of this range are treated as outliers. This applies only to numeric fields.

Parameters

logData

A value of type DM_LogicalDataSpec

fldName

A value of type VARCHAR(128) that is already contained in logData

lowLimit

A value of type DOUBLE , DATE, TIME, or TIMESTAMP, that represents the lower bound value

highLimit

A value of type DOUBLE , DATE, TIME, or TIMESTAMP, that represents the upper bound value

Return Value

The return value is of type DM_LogicalDataSpec

• If fldName is NULL, the value logData is returned.
• If logData does not contain fldName, the following error occurs:

  IDM1201E: A field with the name "Variable1" is not available.

• If fldName is of type DM_Categorical , the following error occurs:

  IDM1206E: The field "Variable1" is not numeric.

• If lowLimit is greater than highLimit or lowLimit equals highLimit, the following error occurs:

  IDM1207E: The lower bound must be smaller than the upper bound.

• If lowLimit is NULL or highLimit is NULL, the value logData is returned. Lower and upper limits for field values are not set. During the training run, lower and upper limits for field values will be calculated by the algorithm according to the values in the data.
• If none of the conditions above apply the value logData is returned. The field with a name equal to fldName is updated with the given values. If the values are of type DATE, TIME, or TIMESTAMP, they are first converted to a DOUBLE value.
