eff.cont-class function

Class eff.cont

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

effCont_new(mean, var, df, x = NULL)

Arguments

• mean: the expected value of the distibution.
• var: the variance 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.cont, with the following components:

mean	the expected value.
var	the variance.
df	the degrees of freedom (effective number of parameters) for model selection .
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, and they must implement methods deff, peff, qeff and reff.
