The NORMSINV() function returns the inverse of the standard normal cumulative distribution. The number must be between 0 and 1 (non-inclusive).
De funksje NORMINV( x) berekkent de ynverze fan de standertnormale kumulative ferdieling. It getal x (in kânsgetal) moat tusken 0 en 1 lizze (iepen ynterfal).
