fitUserDefinedDist-class {optimalThreshold}

An S4 class to fit a user-defined distribution on a vector of marker values.

Description

This class allows to fit a user-defined distribution on the marker values x.

Details

This class is automatically created when the user applies the fit function with the argument distr="user". You never have to create manually this class, it is created internally.

Slots

x

This slot takes in argument the marker values. Numeric argument.

n

Length of x vector (including NA values). Numeric argument.

paraNames

This slot is a character vector of distribution parameter names.

mcmcList

This slot is an mcmc.list object summing up all the sampled parameters of the user-defined distribution.

cdf

This slot is a function that describes the cumulative distribution function of the user-defined distribution.

gradient

This slot is a function that describes the probability density function of the user-defined distribution.

hessian

This slot is a function that describes the fisrt derivative of the probability density function of the user-defined distribution.

mcmc

This slot allows the main function to k,now whether an MCMC algorithm must be performed to sample the distribution parameters from their posterior distribution.
