Calculates the variance of a class probability distribution.


Column Selection
Include the columns containing the class probabilities. The values must sum up to 1 for each data row.
Output column name
Set the name of the appended output column.
In case of invalid input...
Specify the action if a data row of the input is invalid. Invalid could mean a missing value in the input or an invalid distribution (the probabilities must sum up to 1). If fail is selected, the node will fail. Otherwise, the node just gives a warning and puts missing values in the output for the corresponding rows.

Input Ports

Table containing two or more columns containing class probabilities that sum up to 1.

Output Ports

Input data with an appended column that contains the uncertainty score.
