Function qbeta

qbeta<T extends Vectorizable>(
    p: T,
    shape1: number,
    shape2: number,
    options?: TailOptions & NoncentralOption,
): VectorResult<T>
Quantile function of the beta distribution. Equivalent to R's qbeta(p, shape1, shape2, ncp = 0, lower.tail = TRUE, log.p = FALSE).

If ncp is omitted the central distribution is used; otherwise the noncentral beta distribution.
Type Parameters
- T extends Vectorizable
Parameters
- p: T
  Probability (or log probability with logP): a number, number[] or Float64Array. The result has the same shape.
- shape1: number
  First shape parameter (a).
- shape2: number
  Second shape parameter (b).
- options: TailOptions & NoncentralOption = {}
  ncp (see NoncentralOption), lowerTail and logP (see TailOptions).
Returns VectorResult<T>
The quantile(s).
Example
```
qbeta(0.025, 3, 7);          // 0.07485463141969181
qbeta([0.025, 0.975], 3, 7); // [0.07485463141969181, 0.6000935737163121]
```
