lgammaAsymp R Documentation
Asymptotic Log Gamma Function
Description
Compute an n-th order asymptotic approximation to log Gamma function,
using Bernoulli numbers Bern(k) for k in

Usage
lgammaAsymp(x, n)
Arguments
x
numeric vector
n
integer specifying the approximation order.
Value
numeric vector with the same attributes (length() etc) as
x, containing approximate lgamma(x) values.
