NTPOISSONDIST

Returns the Poisson distribution for the specified parameters.

Syntax

NTPOISSONDIST(

  • k,
  • Mean,
  • Cumulative

)

 

Parameters

  • k is the value for which you want the distribution k\;(\geq 0) (Integer).
  • Mean is a parameter of the distribution \nu.
  • Cumulative is a logical value that determines the form of the function. If cumulative is TRUE, NTPOISSONDIST returns the cumulative distribution function; if FALSE, it returns the probability mass function.

Remarks

  • This function is same as Excel function “POISSON”.
