Gamma Distributed Assigner

Assigns a value based on the class column. This value is gamma distributed as defined in the configuration by its peak and scaling parameter. As the peak, please select the value that should be selected most frequently. The scaling parameter can be used to modify the distribution. A value higher than the peak will result in a more compact distribution of the values and a smaller value results in a broader range.
