/*` check_out_of_range functions check that bad parameters
|
|
passed to constructors and functions throw domain_error exceptions.
|
|
|
|
Usage is `check_out_of_range<DistributionType >(list-of-params);`
|
|
Where list-of-params is a list of *valid* parameters from which the distribution can be constructed
|
|
- ie the same number of args are passed to the function,
|
|
as are passed to the distribution constructor.
|
|
|
|
Checks:
|
|
|
|
* Infinity or NaN passed in place of each of the valid params.
|
|
* Infinity or NaN as a random variable.
|
|
* Out-of-range random variable passed to pdf and cdf (ie outside of "range(distro)").
|
|
* Out-of-range probability passed to quantile function and complement.
|
|
|
|
but does *not* check finite but out-of-range parameters to the constructor
|
|
because these are specific to each distribution.
