eff.disc-class function

Class eff.disc

This is the base S3 class for all discrete effectiveness distributions, which is itself a subclass of eff. Function effDisc_new is the constructor of the class.

effDisc_new(p, support, df, x = NULL)

Arguments

• p: the values of the distribution function at the support points.
• support: the support of the distribution.
• df: the effective degrees of freedom of the distribution.
• x: the sample of effectiveness scores used to fit the distribution. Defaults to NULL.

Returns

an object of class eff.disc, with the following components:

mean	the expected value.
var	the variance.
df	the degrees of freedom (effective number of parameters) for model selection .
support	the support of the distribution.
data	the sample data used to fit the distribution, or NULL if none.
model	a list with the family-specific data.

Details

A new distribution family is expected to build new objects through this constructor. Default implementations are readily available for methods deff, peff, qeff and reff.
