distr6 1.2.0

distr6 1.2.0

Major Updates

• None

Minor Updates

Added Functions and Classes

• Added non-central F, T, Chi-Squared, and Beta distributions
• Added WeightedDiscrete distribution. This allows users to supply a data.frame of samples and pdf/cdfs for more efficient usage with empirical discrete estimators (e.g. Kaplan-Meier)

Deprecated Functions

• None

Updated Functions

• Added the common survival parameterisation of Weibull distribution
• Updated the listX functions to make them quicker and functional when distr6 is not attached
• Added suppressMoments argument to Distribution constructor to allow for faster construction

Patches

• Added errormsg argument to assertions so a custom error message can be provided
• Fixed error in quantile function in Empirical that was causing results to be dropped
• Fixed bug in TruncatedDistribution that prevented multivariate distributions being truncated
• Fixed error in variance of Empirical that was calculating sample not population
• Moved rare imports to suggests

distr6 1.1.0

Major Updates

• None

Minor Updates

Added Functions and Classes

• Empirical distribution for distributions arising from observed samples (e.g. from MC sampling methods)
• simulateEmpiricalDistribution: function for sampling without replacement from an Empirical distribution

Deprecated Functions

• ArrayDistribution - This wrapper is now merged with ProductDistribution by adding two new parameters to ProductDistribution that allow for construction either by a distribution list of by naming a distribution and providing a parameter list or data.table

Updated Functions

• Added quantile to Categorical distribution and updated its cdf efficiency
• cdf of discrete distributions evaluated between integers are now evaluated after rounding down and do not return 0, e.g. Binomial$new()$cdf(1.8) == Binomial$new()$cdf(1)
• Added two additional parameters to ProductDistribution: params and distribution, so that it can either function as before or as the ArrayDistribution wrapper which is now deprecated.
• Added two additional parameters to VectorDistribution: params and distribution, so that it can either function as before or as a generalisation to the ArrayDistribution wrapper which is now deprecated.
• Removed automated rounding of numerics when ParameterSet expected integer in setParameterValue
• Added parameter n to strprint and print to clean the print method for distributions (especially wrappers) with multiple parameters
• Added optional vectordist argument to MixtureDistribution for better compatibility with VectorDistribution
• Changed short_name of Uniform, Logistic, Normal, and Triangular kernels to remove Kern. The ClassNames (and thus constructors) remain the same
• listKernels and listSpecialSet now return data.tables with stringsAsFactors = FALSE
• Degenerate distribution re-classified as discrete

Patches

• Bug fix in quantile function of huberization wrapper
• Fixed the rand return of a Vector Distribution (transposed data.table and added column names)
• Fixed spelling mistakes in extension guidelines and removed calls to redundant parameters
• Removed redundant crayon dependency
• Fixed bug in MixtureDistribution that was causing rand to erroneously return integers
• Removed error in Categorical documentation
• Fixed bug in multi-modal Categorical distribution
• summary and print now return self invisibly for better piping
