Origin of Exponential Random Variables What is the origin of exponential random variables An exponential random variable is the interarrival time between two consecutive Poisson events. That is, how much time it takes to go from N Poisson counts to N 1 Poisson counts. Question Find the interarrival time between two people. 819. Regression is a statistical tool to predict the dependent variable with the help of one or more independent variables. And the slope of our line is 37. Each point of data is of t. N(0,1) Gaussian variables (with p 2) and exponentially distributed variables (with 1), satisfy this condition. We study rst the moments of the minimum of a sequence of such. Then the moment generating function is M (t. minimum of three independent exponential random variables, and so is itself an exponential random variable with a rate equal to the sum of the rates. The rate of this exponential random variable is thus 665 17 per hour. Since 10 minutes is 16 hour..
