ChiSquareDistribution

ChiSquareDistribution[ν]
represents a distribution with ν degrees of freedom.

DetailsDetails

  • The probability density for value in a distribution is proportional to for , and is zero for . »
  • For integer ν, the distribution with ν degrees of freedom gives the distribution of sums of squares of ν values independently sampled from a normal distribution.
  • ChiSquareDistribution allows ν to be any positive real number.
  • ChiSquareDistribution allows ν to be a dimensionless quantity. »
  • ChiSquareDistribution can be used with such functions as Mean, CDF, and RandomVariate. »
