Organizing and summarizing search results for youThe exponential distribution is a probability distribution that has a general formula for the probability density function of the form f(x) = (1/β) e^(-(x-μ)/β) where μ is the location parameter and β is the scale parameter. The threshold parameter is another name for the location parameter, and it defines the lowest possible value in an exponential distribution. The double exponential distribution has a probability density function of the form f(x) = e^(-|x-μ|/β)/(2β) where μ is the location parameter and β is the scale parameter.NISThttps://itl.nist.gov/div898/handbook/eda/section3/eda3667.htm1.3.6.6.7.
