## Function name:

FDIST

## Category:

Statistical Analysis

## Summary:

Calculates the area of the right tail of the probability density function for the F-distribution.

## Syntax:

FDIST(**Number**; **degreesFreedom1**; **degreesFreedom2**)

## Returns:

Returns a non-negative real number which is the area of the right tail of the probability density function for the F-distribution.

## Arguments:

**Number** is a real number or a reference to the cell containing that number which is the value for which the F distribution is to be calculated.

**degreesFreedom1** is a real number or a reference to the cell containing that number which is the degrees of freedom in the numerator in the F distribution.

**degreesFreedom2** is a real number or a reference to the cell containing that number which is the degrees of freedom in the denominator in the F distribution.

- If
**Number**is negative or**degreeFreedom1**/**degreeFreedom2**is less than 1, then the function returns an error value. - If
**degreeFreedom1**or**degreeFreedom2**is a non-integer value then the function uses its floor value, i.e. truncates it to an integer.

## Additional details:

- The formula for FDIST is:

If x<0, the function returns an error and it returns the value

otherwise.
