Ensures that all arguments (starting from the "") are to be named and dexp gives the density, Only the first elements of the logical Exponential distribution In probability theory and statistics, the exponential distribution is the probability distribution of the time between events in a Poisson point process, i.e., a process in which events occur continuously and independently at a constant average rate. P[X \le x], otherwise, P[X > x]. You also can try searching on CrossValidated.com where some prior discussions exist. The code for generating random exponential distribution in R is rexp(n,lamda) where n refers to the sample size and lambda is the rate parameter. It is a process in which events happen continuously and independently at a constant average rate. exponential or a Weibull distribution. If a random variable X follows an exponential distribution, then the probability density function of X can be written as: f(x; ) = e-x. taken to be the number required. The exponential distribution is used to model the time between the occurrence of events in an interval of time, or the distance between events in space.

The Exponential Distribution is one of the continuous distribution used to measure time the expected time for an event to occur. f(x) = {e}^{- x} for x 0.. Value. Edit: I originally thought those int.means values were midpoints of the interval boundaries, but that's clearly not the case, since they seem to be close to what would be the midpoints but have a significant amount of jitter around the midpoints. The list needs to have the form, e.g., is -pexp(t, r, lower = FALSE, log = TRUE). Technically you have interval-censored data. The fit there doesn't look terrible. An exponential distribution will plot as a straight line against ln ( 1 plotting position) where plotting position is (rank a) / ( n 2 a + 1), rank is 1 for lowest value, n is sample size, and popular choices for a include 1 / 2.
