WorksheetFunction.Expon_Dist Method (Excel)

Returns the exponential distribution. Use EXPON_DIST to model the time between events, such as how long an automated bank teller takes to deliver cash. For example, you can use EXPON_DIST to determine the probability that the process takes at most 1 minute.

Syntax

식 .Expon_Dist(Arg1, Arg2, Arg3)

식 A variable that represents a WorksheetFunction object.

Parameters

Name	Required/Optional	Data Type	Description
Arg1	필수	Double	X - the value of the function.
Arg2	필수	Double	Lambda - the parameter value.
Arg3	필수	Boolean	Cumulative - a logical value that indicates which form of the exponential function to provide. If cumulative is TRUE, EXPONDIST returns the cumulative distribution function; if FALSE, it returns the probability density function.

Return Value

Double

Remarks

• If x or lambda is nonnumeric, EXPON_DIST returns the #VALUE! error value.

• If x < 0, EXPON_DIST returns the #NUM! error value.

• If lambda ≤ 0, EXPON_DIST returns the #NUM! error value.

• The equation for the probability density function is:

• The equation for the cumulative distribution function is:
