InverseCDF

InverseCDF[dist, q]
gives the inverse of the cumulative distribution function for the symbolic distribution dist as a function of the variable q.

MORE INFORMATION

The inverse CDF at q is also referred to as the q quantile of a distribution.

For a continuous distribution dist the inverse CDF at q is the value x such that CDF[dist, x]=q.

For a discrete distribution dist the inverse CDF at q is the smallest integer x such that CDF[dist, x]≥q.

The value q can be symbolic or any number between 0 and 1.
