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