heavy (version 0.38.196)

heavy.family: Family objects for heavy-tailed distributions

Description

Provide a convenient way to specify the details of the models used by the fitter functions. (i.e., heavyFit, heavyGrubbs, heavyLm, heavyLme and heavyPS functions).

Usage

normal()
Cauchy()
Student(df = 4)
slash(df = 2)
contaminated(epsilon = 0.05, vif = 0.25)

Arguments

df

degrees of freedom for Student-t and slash distributions.

epsilon, vif

percentage of outliers contamination and variance inflation factor.

Details

heavy.family is a generic function to create information about the selected heavy-tailed distribution which is passed to the estimation algorithm.
