is a numeric shape parameter.
| Range | a > 0 |
Details
The GAMINV function
returns the pth quantile
from the gamma distribution, with shape parameter a.
The probability that an observation from a gamma distribution is less
than or equal to the returned quantile is p.
Note: GAMINV is the inverse of
the PROBGAM function.
