NEGBINOM_DIST

Returns the negative binomial distribution, the probability that there will be the specified number of failures before the last success, with the specified probability of a success.

Syntax

expression.NEGBINOM_DIST(arg1, arg2, arg3, arg4);

expression - A variable that represents a ApiWorksheetFunction class.

Parameters

Name	Required/Optional	Data type	Default	Description
arg1	Required	ApiRange | ApiName | number		The number of failures.
arg2	Required	ApiRange | ApiName | number		The threshold number of successes.
arg3	Required	ApiRange | ApiName | number		The probability of a success; a number between 0 and 1.
arg4	Required	ApiRange | ApiName | boolean		A logical value (-true or -false) that determines the function form.\ If it is -true, the function returns the cumulative distribution function.\ If it is -false, the function returns the probability density function.

Returns

number
