Special Cases
The inverse Gaussian and gamma distributions are special cases of the generalized inverse Gaussian distribution for p = -1/2 and b = 0, respectively. Specifically, an inverse Gaussian distribution of the form
is a GIG with, and . A Gamma distribution of the form
is a GIG with, and .
Other special cases include the inverse-gamma distribution, for a=0, and the hyperbolic distribution, for p=0.

Famous quotes containing the words cases and/or special:
“I have always felt that the real purpose of government is to enhance the lives of people and that a leader can best do that by restraining government in most cases instead of enlarging it at every opportunity.”
—Gerald R. Ford (b. 1913)
“When we walk the streets at night in safety, it does not strike us that this might be otherwise. This habit of feeling safe has become second nature, and we do not reflect on just how this is due solely to the working of special institutions. Commonplace thinking often has the impression that force holds the state together, but in fact its only bond is the fundamental sense of order which everybody possesses.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
