- In the context of the exponential distribution, the location parameter (μ) defines the lowest possible value, also known as the threshold. All values must be greater than this threshold. The probability density function of the exponential distribution is given by f(x) = (1/β) * e^(- (x - μ)/β), where β is the scale parameter (often referred to as λ, which equals 1/β)12.Learn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.The threshold parameter defines the lowest possible value in an exponential distribution. Some analysts refer to this parameter as the location. All values must be greater than the threshold.
