Methods

(static) dist(x, deg_freedom1, deg_freedom2, cumulative) → {number}

Returns the F probability distribution.

Parameters:
NameTypeDescription
xnumber

The value at which to evaluate the function.

deg_freedom1number

The numerator degrees of freedom.

deg_freedom2number

The denominator degrees of freedom.

cumulativeboolean

A logical value that determines the form of the function. If cumulative is TRUE, F.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function.

Returns:

the F probability distribution or an error if the arguments are incorrect.

Type: 
number

(static) inv(probability, deg_freedom1, deg_freedom2) → {number}

Returns the inverse of the F probability distribution.

Parameters:
NameTypeDescription
probabilitynumber

A probability associated with the F cumulative distribution.

deg_freedom1number

The numerator degrees of freedom.

deg_freedom2number

The denominator degrees of freedom.

Returns:

the inverse of the F probability distribution or an error if the arguments are incorrect.

Type: 
number

(static) test(array1, array2) → {number}

Returns the result of an F-test.

Parameters:
NameTypeDescription
array1number

The first array or range of data.

array2number

The second array or range of data.

Returns:

the result of an F test or an error if the arguments are incorrect.

Type:
