ELI5: Explain Like I'm 5

Marshall–Olkin exponential distribution

Imagine you are playing with a bunch of toy cars. You line them up and take turns driving them around a track. Sometimes the cars break down after a few laps, and you have to take them out of the game.

Now imagine that instead of toy cars, we're talking about real-life objects that can become obsolete or no longer useful over time - like cars that break down for real, or computers that become outdated. The Marshall-Olkin exponential distribution is a way to understand how quickly these objects deteriorate.

The Marshall-Olkin exponential distribution is a type of probability distribution that describes how different objects deteriorate over time. It uses two parameters, which are like controls on a toy remote: one controls how likely an object is to deteriorate quickly, and one controls how long it takes for an object to deteriorate completely.

If we go back to our toy cars example, let's say one parameter controls how fragile the cars are (more fragile, more likely to break down quickly) and the other controls how many laps they can take before breaking down completely (more laps, longer time before breaking down). By taking these two parameters into account, we can make predictions about how long the cars will last on average, or how likely it is that a specific car will break down after a certain number of laps.

Similarly, using the Marshall-Olkin exponential distribution, we can make predictions about how long a computer will last before becoming outdated, or how likely it is that a car will break down after a certain number of miles on the road. This can help us plan for replacement or maintenance of these objects, and make better decisions about when to invest in new equipment.
