The `gen.trun()`

function allows the user to generate the `d`

, the `p`

, the `q`

, the `r`

and the
`gamlss`

fitting functions of a truncated distribution given that the input `family`

is a current GAMLSS family distribution.

For continuous distributions left truncation at 3 means that the random variable can take the value 3. For discrete distributions left truncation at 3 means that the random variable can take values from 4 onwards. This is the same for right truncation. Truncation at 15 for a discrete variable means that 15 and greater values are not allowed but for continuous variable it mean values greater that 15 are not allowed (so 15 is a possible value).
