Syntax

EXPONDIST( <number>, <number>; <boolean>)

Description

Returns the exponential distribution for a certain value with given lambda.

or

Returns the exponential density function or the cumulative distribution function for the exponential distribution. This function is frequently used used to measure the degree of diversity between two data sets.

The function arguments are:

  • x: The value for which the distribution should be computed (NUMERIC)
  • Lambda: The lambda parameter of the exponential distribution (NUMERIC)
  • Cumulative: Constant indicating the form of the function. If true then the cumulative distribution function is used. If false then the probability mass function is used (BOOLEAN)
Cumulative/BooleanLogical argument which defines the type of distribution to be calculated
TrueUses the cumulative distribution function
FalseUses the probability density function

Example

Common Errors

#NUM!-

Occurs if either:

  • The x value is less than 0
  • The numerator or denominator is less than 1
#VALUE!-Occurs if the argument type isn't numeric
