Sub NextInvoice() Range(“E5”).Value = Range(“E5”).Value + 1 Range(“A20:E39”).ClearContents End Sub. Macro #2: Save invoice with new name. Sub SaveInvWithNewName() Dim NewFN As Variant The most common random number generator (RNG) in Excel is the RAND function. There are two ways to enter RAND. Because it’s such a short function, typing it manually is arguably the quickest, and a general rule of thumb is to learn the long-hand version first, thereby making you worthy of the shortcut. The RAND syntax is: =rand (). The StdRandom class provides static methods for generating random number from various discrete and continuous distributions, including uniform, Bernoulli, geometric, Gaussian, exponential, Pareto, Poisson, and Cauchy.

If Excel doesn't have a random number generator for the binomial distribution (I didn't look), it's easy to make a simple one. Remember that a sample from a binomial distribution with parameters n and p is just the sum of n variables which are Bernoulli variables (i.e. simple coin tosses) with probability p.
Jun 04, 2012 · problem. A number of methods were developed to deal with such problem, and among them, Quasi-Poisson and Negative Binomial are the most popular methods perhaps due to that major statistical softwares contain such functions. Unlike Negative Binomial distribution, there is no function for generating Quasi-Poisson distributed random variable in R.
