Generating Random Numbers from an Exponential Distribution
November 6th, 2017
Reliability HotWire is a monthly eMagazine by ReliaSoft providing information and tips on how to best improve your reliability practices and get the most out of ReliaSoft’s tools for reliability and life data analysis.
This Month’s Hot Topic
Generating Random Numbers from an Exponential Distribution
The probability density function (pdf) can be very helpful in analyzing data sets. There are numerous ways to think about the pdf. For example, it was presented from the perspective of histograms in Reliability Hotwire Issue 12. In this article, we consider the pdf from the perspective of a random number generator, and present two ways to generate random numbers from an exponential distribution. First, we will show you how to generate random numbers from an exponential distribution using ReliaSoft Weibull++ by HBM Prenscia. Second, assuming we can generate random numbers between 0 and 1, we will show you how to manually generate random numbers from an exponential distribution using those random numbers. This approach is the basic algorithm used by the Monte Carlo tool; as you will see, the tool can save you considerable time and effort.
