Determination of statistical tolerance intervals”. Such an interval, would however, not be of much help to a person renting one of these cars and wondering whether the full gallon tank of gas will suffice to carry him the miles to his destination.

So consider once again a proverbial EPA mileage test scenario, in which several nominally identical autos of a particular model are tested to produce mileage figures y 1y 2.
Bayesian probability prior posterior Credible interval Bayes factor Bayesian estimator Maximum posterior estimator. The prediction interval only bounds a single future sample, however, whereas a tolerance interval bounds the entire population equivalently, an arbitrary sequence of future samples.
Tolerance interval – Wikipedia
John Wiley and Sons.
In other words, a prediction interval covers a specified proportion of a population on averagewhereas a izo interval covers it with a certain confidence levelmaking the tolerance interval more appropriate if a single interval is intended to bound multiple future samples. You may find similar items within these categories by selecting from the choices below:. We note that exp mu is the median air lead level.
Whereas a confidence interval’s size is entirely due to sampling errorand will approach a zero-width interval at the true population parameter as sample size increases, a tolerance interval’s size is due partly to sampling error and partly to actual variance in the population, and will approach the population’s probability interval as sample size increases. What is required is a tolerance interval; more specifically, an upper tolerance limit. YoungBook Reviews: Pages using web citations with no URL Articles to be expanded from July All articles to be expanded Articles using small message boxes.
The tolerance isk is related to a prediction interval in that ios put bounds on variation in future samples. Now suppose we 16269–6 to predict the air lead level at a particular area within the laboratory. Views Read Edit View history.
A confidence interval for mu can be constructed the usual way, based on sio t -distribution ; this in turn will provide a confidence interval for the median air lead level. The meaning and interpretation of these intervals are well known. Grouped data Frequency distribution Contingency table.

The tolerance interval differs from a confidence interval in that the confidence interval bounds a single-valued population parameter the mean or the 16629-6for example with some confidence, while the tolerance interval bounds the range of data values that includes a specific proportion of the population.
Simple linear regression Ordinary least squares General linear model Bayesian regression. Theory, Applications, 12669-6 Computation. The confidence interval and prediction interval cannot answer this question, since the confidence interval is only for the median lead level, and the prediction interval is only for a single lead level.

It was noted that the log-transformed lead levels fitted a normal distribution well that is, the 16296-6 are from a lognormal distribution.
Observational study Natural experiment Quasi-experiment. A tolerance interval is a statistical interval within which, with some confidence level, a specified proportion of a sampled population falls.
