represents an inverse 
distribution with degrees of freedom.
InverseChiSquareDistribution[, 
]
represents a scaled inverse 
distribution with degrees of freedom and scale .
Details
- The inverse
distribution InverseChiSquareDistribution[] is the distribution followed by the inverse of a 
-distributed random variable with degrees of freedom. - The quantity
follows a scaled inverse 
distribution InverseChiSquareDistribution[, ] where 
follows a 
distribution with degrees of freedom. » - The inverse
distribution is commonly used in normal models for Bayesian data analysis. - InverseChiSquareDistribution allows and to be any positive real numbers.
- InverseChiSquareDistribution can be used with such functions as Mean, CDF, and RandomVariate.
