FDIST

Calculates the left-tailed F probability distribution for two data sets with given input x.

 

Sample Usage

FDIST(13.5,5,6,TRUE)
FDIST(A1,A2,A3,FALSE)

Syntax

FDIST(number, degrees_freedom1, degrees_freedom2, cumulative)

  • number - The value at which to evaluate the function.
  • degrees_freedom1 - The numerator of the number of degrees of freedom.
  • degrees_freedom2 - The denominator of the number of degrees of freedom.
  • cumulative - A logical value that determines the form of the function.

Examples

FDIST(13.5,5,6,TRUE) returns a value of 0.99675.
FDIST(13.5,5,6,FALSE) returns a value of 0.0006.

 

Notes

  • number must be a positive numeral.
  • degrees_freedom1 and degrees_freedom2 must be numeric.
  • degrees_freedom1 and degrees_freedom2 must be greater than 1 and less than 10^10.
  • degrees_freedom1 and degrees_freedom2 are truncated to integer(s) if non-integer(s) are provided.
  • Set cumulative to TRUE to use the cumulative distribution function, and set it to FALSE to use the probability density function.
