| Inverse Gaussian(rmutil) | R Documentation |
These functions provide information about the inverse Gaussian
distribution with mean equal to m and dispersion equal to s.
dinvgauss gives the density, pinvgauss gives the distribution
function, hinvgauss gives the hazard function.
The inverse Gaussian distribution has density
f(y) = 1/sqrt(2 pi s y^3) e^-((y - m)^2/(2 y s^2 m^2))
where m is the mean of the distribution and s is the dispersion.dinvgauss(y, m, s) pinvgauss(q, m, s) hinvgauss(y m, s)
