WebRecall the cdf of X is F X ( t) = P ( X ≤ t). Therefore, for t < 1 2, we have F X ( t) = ∫ 0 t 2 − 4 x d x = 2 x − x 2 0 t = 2 t − 2 t 2 and for t ≥ 1 2 we have F X ( t) = ∫ 0 1 / 2 2 − 4 x d x + ∫ 1 / 2 t 4 x − 2 d x = 1 2 + ( 2 x 2 − 2 x) 1 / 2 t = 2 t 2 − 2 t + 1 Thus, the cdf of X is WebMay 16, 2016 · F ( x) = e − e − x. and it can be easily inverted: recall natural logarithm function is an inverse of exponential function, so it is instantly obvious that quantile function for Gumbel distribution is.

In probability theory and statistics, the exponential distribution or negative exponential distribution is the probability distribution of the time between events in a Poisson point process, i.e., a process in which events occur continuously and independently at a constant average rate. It is a particular case of the gamma distribution. It is the continuous analogue of the geometric distribution, …
