-/*
- * Paretoormal distribution table generator
- *
- * This distribution is simply .25*normal + .75*pareto; a combination
- * which seems to match experimentally observed distributions reasonably
- *  well, but is computationally easy to handle.
- * The entries represent a scaled inverse of the cumulative distribution
- * function.
- *
- * Taken from the uncopyrighted NISTnet code.
