Functions for distributions

A distribution is a structured data type that is also available as a value type for user-defined fields. It defines a mapping from string → number, where the numerical values usually form a percentage distribution. This data type is used, for example, to define weightings for asset class splitting (fund splitting).

Distribution.AddWeight[Category:String;Weight:Number]→Distribution

Result: The AddWeight function adds a pair of values to a distribution. The weight is generally not interpreted as a percentage, but in relation to the total weight of the distribution.

Distribution.GetKeyList→List(IndexString)

Result: The GetKeyList function returns the list of all category names that are defined in the distribution with a non-zero weight.

Distribution.GetWeight[Category:String]→Number

Result: The GetWeight function returns the weight defined in the distribution for the category. The weight is 0 for all categories not explicitly defined.

MakeDistribution→Distribution

Result: The MakeDistribution function returns an empty distribution.

Distribution.NormalizedWeight[Category:String]→Number

Result: The NormalizedWeight function returns the normalized weight defined in the distribution for the category, as a quotient of weight and total weight sum.
