LOGNORM.DIST Formula. The distribution function syntax is defined as LOGNORM.DIST(x,mean,standard_dev,cumulative) in excel which returns the lognormal distribution of x, with given parameters for the mean and standard deviation of the natural logarithm, Ln(x). Normal distribution The normal distribution is the most widely known and used of all distributions. Because the normal distribution approximates many natural phenomena so well, it has developed into a standard of reference for many probability problems. I. Characteristics of the Normal distribution • Symmetric, bell shaped The normal distribution is a symmetric distribution. That is, If we were to vertically slice this distribution, we will get two equal halves. Generally speaking, a distribution gets identified by where on the horizontal axis it is placed and how spread out or peaked it is. Normal distribution values in Excel. To compute the values of the normal distribution function , we can use the built-in Excel function NORM.S.DIST(). For example, if we need to compute and the value is stored in cell A1, we can type in another cell: =NORM.S.DIST(A1) Normal distribution values in Matlab In Excel or Google Docs you can readily construct a Cumulative Distribution Function for the Normal distribution using the NORMDIST function (X, Mean, Standard Deviation). I am trying to do the same for a Lognormal distribution using the LOGNORMALDIST function that has the same parameters (X, Mean, Standard Deviation).
