NoncentralChiSquareDistribution
NoncentralChiSquareDistribution[
, 
]
represents a noncentral 
distribution with degrees of freedom and noncentrality parameter .
Details
- The probability density for value
is proportional to ![ⅇ^( (-lambda-x)/2) x^(nu/2-1) TemplateBox[{{nu, /, 2}, {{(, {x, , lambda}, )}, /, 4}}, Hypergeometric0F1Regularized]](Files/NoncentralChiSquareDistribution.en/3.png "ⅇ^( (-lambda-x)/2) x^(nu/2-1) TemplateBox[{{nu, /, 2}, {{(, {x, , lambda}, )}, /, 4}}, Hypergeometric0F1Regularized]")
for 
and zero otherwise. - NoncentralChiSquareDistribution allows and to be any positive real numbers.
- NoncentralChiSquareDistribution can be used with such functions as Mean, CDF, and RandomVariate. »
