... Systems of equations are used to analytically represent physical problems that involve the interaction of various properties. Although not all physical problems can be represented using a linear system, the solution to many problems either have this form or can be approximated by such a system. Ther ...

However, in other cases, when we want to make estimates of the population parameters with a known level of precision, we must use probability sample p ...

Resampling (statistics)

In statistics, resampling is any of a variety of methods for doing one of the following: Estimating the precision of sample statistics (medians, variances, percentiles) by using subsets of available data (jackknifing) or drawing randomly with replacement from a set of data points (bootstrapping) Exchanging labels on data points when performing significance tests (permutation tests, also called exact tests, randomization tests, or re-randomization tests) Validating models by using random subsets (bootstrapping, cross validation)Common resampling techniques include bootstrapping, jackknifing and permutation tests.
