WitrynaThe intuitive way to think about this distribution, is to consider the ith order statistic in a sample of N. Now in order for the value of the ith order statistic of a random variable X to be equal to x we need 3 conditions: i − 1 values below x, this has probability FX(x) for each observation, where FX(x) = Pr(X < x) is the CDF of the random ... WitrynaThe kth-order statistic, denoted X (k), is the the kth-largest realization, among n, of a random variable X. In particular, the ﬁrst order statistic is the maximum of n draws, the second order statistic is the second highest of n draws, and the nth-order statistic is the minimum of n draws. Order statistics, for reasons that should be ...
