适用范围:This part of ISO 16269 specifies methods of determining prediction intervals for a single continuouslydistributed variable. These are ranges of values of the variable, derived from a random sample of size H, forwhich a prediction relating to a further randomly selected sample of size m from the same population may bemade with a specified confidence.Three different types of population are considered, namely:a) normally distributed with unknown standard deviation;b) normally distributed with known standard deviation;c) continuous but of unknown form.For each of these three types of population, two methods are presented, one for one-sided prediction intervalsand one for symmetric two-sided prediction intervals. In all cases, there is a choice from among six confidencelevels.The methods presented for cases a) and b) may also be used for non-normally distributed populations thatcan be transformed to normality.For cases a) and b) the tables presented in this part of ISO 16269 are restricted to prediction intervalscontaining all the further m sampled values of the variable. For case c) the tables relate to prediction intervalsthat contain at least m- r of the next m values, where r takes values from 0 to 10 or 0 to m 1, whicheverrange is smaller.For normally distributed populations a procedure is also provided for calculating prediction intervals for themean of m further observations.
