B
- BootstrappingConceptBootstrapping Method, Bootstrap Resampling
- Bootstrapping is a resampling method that approximates the sampling distribution of an estimator by repeatedly recalculating it on samples drawn with replacement from the observed data or generated from a fitted model.
C
- Cross-ValidationConceptOut-of-Sample Validation, Resampling Validation
- Cross-validation is a resampling procedure that repeatedly trains a predictive model on one part of a dataset and evaluates it on held-out observations to estimate performance under a specified data-splitting scheme.
J
- JackknifeConceptLeave-One-Out Estimation, Quenouille Method
- A resampling technique estimating a statistic's variability by systematically recalculating it after removing one observation at a time.
P
- Permutation TestConceptRandomisation Test, Resampling Test
- A non-parametric hypothesis test determining significance by repeatedly rearranging observed data labels to build an empirical distribution under the null hypothesis.
R
- ResamplingTermSample Reuse, Repeated Subsampling
- A family of statistical methods that draw repeated samples from observed data to estimate uncertainty or validate models, including the bootstrap, jackknife and cross-validation.
