Creates a probability density function from a current `gamlss.family`

distribution to be used for fitting a censored or interval response variable.

`cens.d(family = "NO", type = c("right", "left", "interval"), ...)`

Returns a modified d family function.
The argument of the original function `d`

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`

and in the package`gamlss.dist`

.- type
whether

`right`

,`left`

or in`interval`

censoring is required, (right is the default)- ...
for extra arguments

This function is used to calculate the likelihood function for censored data.
This function is not supposed to be used on its own but it is used in function `gen.cens`
