The probability density function of a two-parameter exponential distribution is given by: f(t;[mu],[theta]) = [1/[theta]]exp{-(t-[mu])/[theta]}, t[greater than or equal to][mu] and t[greater than or equal to]0 Where: [mu] = The location parameter [theta]>0 = The scale parameter The probability distribution function is: F(t;[mu],[theta]) = 1-exp{-(t-[mu])/[theta]}.
