Web1. For a discrete random variable X with support on some set S, the expected value of X is given by the sum. E [ X] = ∑ x ∈ S x Pr [ X = x]. And the expected value of some function g of X is then. E [ g ( X)] = ∑ x ∈ S g ( x) Pr [ X = x]. In the case of a Poisson random variable, the support is S = { 0, 1, 2, …, }, the set of ... WebCumulative Required. A logical value that determines the form of the function. If cumulative is TRUE, LOGNORM.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function. Remarks If any argument is nonnumeric, LOGNORM.DIST returns the #VALUE! error value.
