Gamma inverse cumulative distribution function
No known analytical solution exists for the integral equation shown in Gamma icdf.
gaminv
uses an iterative approach (Newton's method) to converge on
the solution.
gaminv
is a function specific to the gamma distribution.
Statistics and Machine Learning Toolbox™ also offers the generic function icdf
, which supports various probability distributions. To use
icdf
, create a GammaDistribution
probability distribution object and pass the object as an
input argument or specify the probability distribution name and its parameters. Note
that the distribution-specific function gaminv
is faster than
the generic function icdf
.
