If instead of lightning strikes we were trying to model the inter-arrival times of high tides or trains on a regularly scheduled route, we shouldn’t use the exponential distribution since these are not random events. Mean Time to Failure Example 2: The time until failure of a particul...

Analysts frequently use the exponential distribution to model the amount of time between independent events. In this type of study, theprobability density functionassumes that events occur at a constant rate on average over time. For example,reliabilityanalysts use this distribution to model failure ti...
Example 1: Generate/Create Random Values From an Exponential Distribution Example 2: Determine the Probability Density Function of an Exponential Distribution Example 3: Determine the Cumulative Distribution Function of an Exponential Distribution Example 4: Determine the Percent Point Function of an Exponen...
The exponential distribution is a one-parameter family of curves. The exponential distribution models wait times when the probability of waiting an additional period of time is independent of how long you have already waited. For example, the probability that a light bulb will burn out in its ne...

Summary The exponential distribution is typically used to model waiting times, for example, to model survival times of cancer patients or life times of machine components. The exponential distribution is memoryless in the sense that the remaining waiting time at a specific time point is independent ...
2-Parameter Exponential RRX Example Using the same data set from the RRY example above and assuming a 2-parameter exponential distribution, estimate the parameters and determine the correlation coefficient estimate, , using rank regression on X. ...
For example: After watching a bank teller interact with a customer for one minute, the probability of completing the transaction the next minute is the same as it was one minute ago. Summary of Exponential Distribution The exponential distribution is a type of probability distribution that accounts...
We will show in the Solved Problems section that the distribution of XX converges to Exponential(λ)Exponential(λ) as ΔΔ approaches zero.To get some intuition for this interpretation of the exponential distribution, suppose you are waiting for an event to happen. For example, you are at a...
