Probability Functions
ChiSquare Quantile
Accepts three arguments: a probability p, a degrees of freedom, and a noncentrality parameter. It returns the
p th quantile from the Chi-squared distribution with the specified noncentrality parameter and degrees of
freedom. For example, the expression ChiSquare Quantile(.95, 3.5, 4.5) returns the 95% quantile from the
Chi-squared distribution centered at 4.5 with 3.5 degrees of freedom. The expression evaluates as 17.50458.
The ChiSquare Quantile function accepts integer and noninteger degrees of freedom. It is centered at 0 by
default. The ChiSquare Quantile function is the inverse of the ChiSquare Distribution function.
Dunnett P Value
Returns the p-value from Dunnett’s multiple comparison test.
Dunnett Quantile
Returns the quantile needed in Dunnett’s multiple comparison tests.
F Density
Accepts a quantile argument from the range of values for the F-distribution, numerator and denominator
degrees of freedom arguments, and an optional noncentrality parameter. It returns the value of the F-density
function (pdf) for the arguments.
F Distribution
Accepts four arguments: a quantile, a numerator and denominator degrees of freedom, and a noncentrality
parameter. It returns the probability that an observation from the F-distribution with the specified
noncentrality parameter and degrees of freedom is less than or equal to the given quantile. For example, the
expression F Distribution(3.32, 2, 3) returns the probability that an observation from the central
F-distribution with 2 degrees of freedom in the numerator and 3 degrees of freedom in the denominator is
less than or equal to 3.32. The expression evaluates as 0.82639.
The F-distribution function accepts integer and noninteger degrees of freedom. By default, the non-central
parameter is set to 0. The F-distribution function is the inverse of the F Quantile function.
F Quantile
Accepts four arguments: a probability p, a numerator and denominator degrees of freedom, and a
noncentrality parameter. It returns the p th quantile from the F-distribution with the specified noncentrality
parameter and degrees of freedom. For example, the expression F Quantile(0.95, 2, 10, 0) returns the 95%
quantile from the F-distribution centered at 0 with 2 degrees of freedom in the numerator and 10 degrees of
freedom in the denominator. The expression evaluates as 4.1028.
The F Quantile function accepts integer and noninteger degrees of freedom. By default, the non-central
parameter is set to 0. The F Quantile function is the inverse of the F Distribution function.
Frechet Density
Returns the density at x of a Fréchet distribution with location mu and scale sigma.
