public class ExponentialTimesCarExperiment
extends Experiment
implements java.io.Serializable

This class models the Times between Cars driving on a highway. The times between cars follows Exponential distribution with some rate-parameter lambda, Exp(lambda). The expected time between two cars is 1/lambda! This Exp(lambda) distribution is a special case of Gamma( k , theta ) distribution. i.e., Gamma(k=1, theta = 1/lambda) ~ Exponential(lambda); http://en.wikipedia.org/wiki/Gamma_distribution#Specializations* Note that the "Number of Arrivals" in a fixed time period follows Poisson distribution.
