R Package for Pairwise Preference Elicitation

Documentation for package ‘prefeR’ version 0.1.3

%<%	A helper function to add in preferences in a user-friendly way.
%=%	A helper function to add in preferences in a user-friendly way.
%>%	A helper function to add in preferences in a user-friendly way.
.calculateLogProb	Calculates the log probability of seeing a given set of preferences
.estimateEntropy	Calculates the expected posterior entropy of the prefel object if x and y are compared. Ignores the odds of indifference preferences, as using them would increase runtime 50% without much gain.
.getLogIndifProb	Evaluates the likelihood of the observed indifference preferences
.getLogStrictProb	Evaluates the likelihood of the observed strict preferences
.sampleEntropy	Calculates the entropy of a matrix of samples.
BayesPrefClass	An object containing all data necessary for preference elicitation.
Exp	A convenience function for generating Exponential priors.
Flat	A convenience function for generating a flat prior.
infer	A function that estimates the user's underlying utility function.
Normal	A convenience function for generating Normal priors.
prefEl	A shortcut to create objects of the class BayesPrefClass.
suggest	Suggests a good comparison for the user to make next.
