Beta Distributed Assigner

Assigns a value based on the class column. This value is beta distributed as defined in the configuration by its peak and scaling parameter p. As the peak, please select the value that should be selected most frequently. The scaling parameter can be used to modify distribution: a value between 0 and 1 will result in a broader range; a value above 1 results in a more compact distribution of the values.
