It is also known as the log-Weibull distribution and the double exponential distribution (a term that is alternatively sometimes used to refer to the Laplace distribution). beta-binomial | The rest of the iteration is done by highlighting the range C3:J19 and pressing Ctrl-R and highlighting the range D2:J2 and pressing Ctrl-R. Once the beta value is obtained, the estimate for mu (cell J20) is obtained using the following formula. The moments estimates of $\mu$ and $\sigma$ are often used as initial values.

Now assume that we have $n$ non-overlapping blocks of time with the same \sigma_M = \sigma_Y. Maxwell-Boltzmann | X \ell \ell(\widehat{\lambda}(\sigma_Y),\,\sigma_Y), We now explain how we obtained the first improved guess for beta of .347061 (cell D2). of $\mu$ and $\sigma$ are often used as initial values. i.e. The pdf of the Gumbel distribution is: with cdf: The parameter μ is the mode of the distribution, so the sample mode (if easily determined) in conjunction with the sample mean may be used to assist in estimation. $M_i \sim \text{Gumbel}(\mu_M,\,\sigma_M)$ with relation with the Peak Over Threshold (POT) model.
