# • ### MappedTransformedDistribution

Transform a statistical distribution by applying the same function to all of its arguments

• ### PowerTotal

Compute the total of a list of numbers all taken to some power

• ### PowerMean

Compute the mean of a list of numbers all taken to some power

• ### QueryTreeForm

Present a query as a tree

• ### JoinRest

An operator that performs a Join of its argument with the sequence of lists it is provided

• ### MixtureCategoricalDistribution

Create a mixture distribution of categorical distributions and output it as a new CategoricalDistribution

• ### TimeShiftedDistribution

A derived distribution useful in actuarial science

• ### ConditionalCategoricalDistribution

Obtain a conditional categorical distribution formed by restricting the domain of a categorical distribution

• ### QuantileOperator

An operator form of the Quantile function

• ### MeanMedianLogNormalDistribution

Create a lognormal distribution using mean and median as parameters instead of the conventional parameters

• ### MapLevel

Create an operator that maps a function over data at a specified level

• ### Terse

An operator form of Short

• ### CorrespondingIntegers

Create a list of positive integers containing as many elements as the expression to which it is applied

• ### ItemCounts

A two-argument form of Counts that gives an association between a set of provided keys and the number of times those keys appear in a list

• ### ConstantAssociation

Create an association whose values are all a constant

• ### ActuarialCommutation

Creates an Association containing values for the six standard commutation functions used in actuarial mathematics

• ### EntityClassDimensions

Produce a list with the number of entities in an entity class and the number of properties possessed by each entity therein

• ### ValueMapIndexed

Create an association from a set of values, using a map-indexed function on those values to form the keys

• ### HedgesG

Computes the Hedges' g statistic measuring an "effects size" difference between two lists of data

• ### MapReduceOperator

Like an operator form of GroupBy, but where one also specifies a reducer function to be applied

• ### PairMap

Map a function to pairs formed from a list and another function

• ### ReverseAccumulate

Replace each element of a list with the sum of the elements in the original list that are not to the left of that element

• ### ShowQuotes

Style the output so that quotation marks (as string characters) appear

• ### ApplyLevel

Create an operator that applies a function over data at a specified level

• ### PooledStandardDeviation

Compute the pooled standard deviation of multiple lists of data

Create a beta distribution using the mean and a measure of its spread as parameters instead of using the conventional parameters

• ### JoinMost

An operator that joins in front of its arguments the sequence of lists it is provided

• ### PooledVariance

Compute the pooled variance of multiple lists of data

• ### MortalityConvert

Convert vector descriptions of mortality into another representation

• ### ResetDataset

Force a reanalysis of the types contained in a Dataset, sometimes leading to a different presentation of the data

• ### ValueMap

Similar to AssociationMap but maps over a given set of values to obtain keys rather than vice versa

• ### MapSlice

Provide the part specifications to a mapped function as a sequence of arguments after the first one

• ### KeyMapIf

Map a function conditionally over keys in an association
