- ChiSquared[ <Degrees of Freedom d>, x ]
- Creates probability density function (pdf) of Chi squared distribution with d degrees of freedom.
- ChiSquared[ <Degrees of Freedom>, x, <Boolean Cumulative> ]
- If Cumulative is true, creates cumulative density function of Chi squared distribution, otherwise creates pdf of Chi squared distribution.
- ChiSquared[ <Degrees of Freedom d>, <Variable Value v> ]
- Calculates the value of cumulative distribution function of Chi squared distribution at v, i.e. the probability P(X≤v) where X is a random variable with Chi squared distribution with d degrees of freedom.
- Note: Returns the probability for a given x-coordinate's value (or area under the Chi squared distribution curve to the left of the given x-coordinate).
CAS Syntaxes
In CAS View only following syntax is supported:
- ChiSquared[<Degrees of Freedom d>, <Variable Value v>]
- Calculates the value of cumulative distribution function of Chi squared distribution at v, i.e. the probability P(X≤v) where X is a random variable with Chi squared distribution with d degrees of freedom.
