Inverse Gaussian {rmutil} | R Documentation |
These functions provide information about the inverse Gaussian
distribution with mean equal to m
and dispersion equal to
s
: density, cumulative distribution, quantiles, log hazard, and
random generation.
The inverse Gaussian distribution has density
f(y) = 1/sqrt(2 pi s y^3) e^-((y - m)^2/(2 y s m^2))
where m is the mean of the distribution and s is the dispersion.
