LGamma
(Redirected from Lgamma)
LGamma(X)
Returns the Log Gamma function of «X». Without numeric overflow, this function is exactly equivalent to Ln(GammaFn(X))
.
Because the gamma function grows so rapidly, it is often much more convenient to use LGamma() to avoid numeric overflow.
LogBetaFn(x)
To compute Ln(BetaFn(a,b))
, you should instead use
which is less susceptible to numeric underflow for really large values of a
and b
.
