Probability Density Function The general formula for the probability density function of the exponential distribution is $$f(x) = \frac{1} {\beta} e^{-(x - \mu)/\beta} \hspace{.3in} x \ge \mu; \beta > 0$$ where μ is the location parameter and β is the scale parameter (the scale parameter is often referred to as λ which equals 1/β).The case where μ = 0 and β = 1 is called the standard. Stack Exchange network consists of Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share . The negative exponential distribution can also be presented in the form () F (t) = 1 − exp [ − (t / MTTF) ] where F (t) is the cumulative distribution of the time to failure and MTTF is the mean time to failure. The negative exponential distribution of the times . Exponential functions like these all have certain things in common. First, their domain is equal to all real numbers. So any number can go in for x—positive or negative, rational or irrational. 1 Interestingly, when a negative number is put in for x, the function itself still .
