Syntax

NTLOGNORMDIST(

  • x,
  • M,
  • S,
  • Cumulative

)

 

Parameters

  • x is the value for which you want the distribution (x>0).
  • M is a parameter of the distribution M.
  • S is a parameter of the distribution S\;(>0).
  • Cumulative is a logical value that determines the form of the function. If cumulative is TRUE, NTLOGNORMDIST returns the cumulative distribution function; if FALSE, it returns the probability mass function.
