SpletThe Excel NORM.DIST function returns values for the normal probability density function (PDF) and the normal cumulative distribution function (CDF). The PDF returns values of … SpletAll distributions have a PDF function. Some have a CDF. Some have an inverse CDF. There’s a general pattern to function names, but there are exceptions. Probability function names in Excel typically consist of a base name and a suffix. The base name is an abbreviation of the distribution name. The suffix is either DIST or INV.
