The Gamma distribution is a continuous probability distribution commonly used in statistics to model waiting times and life durations. It is defined by two parameters: shape (k) and scale (θ). The shape parameter determines the form of the distribution, while the scale parameter stretches or compresses it. This distribution is particularly useful in fields like queueing theory and reliability engineering, where it helps analyze processes that involve waiting times or lifetimes of objects. The Gamma distribution can also be related to other distributions, such as the Exponential distribution and the Chi-squared distribution, making it versatile in statistical applications.
