	~~When~~ the ~~sample size is small, asymptotic results given by some traditional methods may not be valid~~. ~~In such situations~~, ~~the asymptotic~~ [~~[p-value~~]~~]s may differ substantially~~ from the ~~exact p~~-~~values~~. ~~Hence asymptotic and~~ other ~~approximate results may lead to unreliable and misleading conclusions~~.

	~~== The Approach ==~~
	~~All classical statistical procedures are constructed using statistics which depend only on observable random vectors, whereas Generalized Estimators, Tests~~, and ~~Confidence Intervals used in exact statistics take advantage~~ of the ~~observable random vectors~~ and the ~~observed values both, as in~~ the ~~Bayesian approach but without having~~ to ~~treat constant parameters as random variables~~. ~~For example, in sampling from a normal population with mean~~ <~~math~~>~~\mu~~<~~/math~~> and ~~variance <math>\sigma ^2<~~/~~math>, suppose <math>\overline{X}<~~/~~math> and <math>S ^2<~~/~~math> are~~ the ~~sample mean and~~ the ~~sample variance~~. ~~Then~~, it is ~~well known~~ that
	~~<math> Z = \sqrt{n}(\overline{X} - \mu)/ \sigma \sim N(0,1)</math>~~
	~~and that~~
	~~<math>U = n S^2 / \sigma^2 \sim \chi^2 _ {n-1}</math>.~~
	~~Now suppose~~ the ~~parameter of interest is~~ the ~~coefficient of variation,~~ <~~math~~>~~\rho = \mu /\sigma~~ <~~/math~~>. ~~Then~~, ~~we can easily perform exact tests and exact confidence intervals~~ for ~~<math>\rho</math> based on~~ the ~~generalized statistic~~
	~~<math>R = \frac {\overline{x} S} {s \sigma} - \frac{\overline{X}- \mu} {\sigma}~~
	~~= \frac {\overline{x}} {s} \frac {\sqrt{U}} {\sqrt{n}} ~-~ \frac {Z} {\sqrt{n}} </math>~~,
	~~where~~ <~~math~~>~~\overline{x}~~<~~/math~~> is the ~~observed value~~ of <~~math~~>~~\overline{X}~~<~~/math~~> ~~and <math>S</math> is~~ the ~~observed value~~ of ~~<math>s</math>~~. ~~Exact inferences~~ on ~~<math>\rho<~~/~~math> based on probabilities and expected values of <math>R<~~/~~math> are possible because its distribution and the observed value are both free of nuisance parameters~~.

	==~~Generalized p-values~~==

	~~Classical statistical methods do not provide exact tests to many statistical problems such as testing Variance Components and ANOVA under unequal variances~~. ~~To rectify this situation, the [[generalized p~~-~~value]]s are defined as an extension~~ of ~~the classical p~~-~~values so that one can perform tests based on exact probability statements valid for any sample size~~.
