cens.q: Censored Inverse Cumulative Probability Density Function of a gamlss.family Distribution

Description

Creates the inverse cumulative density function from a current gamlss.family distribution suitable for censored or interval response variable data. This is a dummy function identical to the uncensored one but it is needed for consistency in centile estimation from censored data.

Usage

cens.q(family = "NO", ...)

Value

Returns a modified q family function. The argument of the original function q function are the same.

Arguments

family: a gamlss.family object, which is used to define the distribution and the link functions of the various parameters. The distribution families supported by gamlss() can be found in gamlss.family.
...: for extra arguments

Details

This is dummy function, used only to calculate centiles from censored response variable. This function is not supposed to be used on its own but is used by the function gen.cens.
