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.

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

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

- 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`

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`
