Definitions:

Exponential Distribution

The exponential distribution is a continuous probability distribution used to model the time or space between events in a Poisson process.

Density Function

A mathematical function that specifies the probability of a random variable taking on certain values.

Parameter

A quantity that influences the output or behavior of a mathematical function or statistical model, often fixed during the analysis.

Exponential Random Variable

A type of continuous random variable that is used to model time until an event occurs, with a constant hazard rate.
