4.The Latin hypercubesampling isa stratified-random procedure, provides an efficient way of sampling variablesfrom their distributions. It can be summarized as: Step1 divide the cumulativedistribution of each variable into N equiprobable intervals; Step2 from eachinterval select a value randomly, for the ith interval, the sampled cumulative probability can be written as: Probi=(1/ N) ru+ ( i– 1)/N where ru is uniformly distributedrandom number ranging from 0 to 1; Step3 transform the probability values sampledinto the value x using the inverse of the distribution function F-1:x= F-1(Prob); Step4 the N values obtained for each variable x are paired randomly (equally likely combinations)with the ns values of the othervariables.
想问这个ns values 是啥意思啊？
