jackknife
The jackknife (also known as the Quenouille jackknife) is a statistical method used for estimating a parameter from a sample of observations by systematically leaving out one observation at a time and recalculating the estimate. The aim of this method is to reduce bias and provide more accurate confidence intervals. This resampling method is used in fields like econometrics, computational statistics, and machine learning. Also, a jackknife is a compact folding knife that typically contains multiple blades or tools. It's commonly used for tasks like cutting ropes, opening packages or peeling fruits. It was originally designed as a portable utility knife for sailors. The term 'jackknife' can also refer to a specific position or maneuver in activities like diving, truck driving, yoga or gymnastic where the body is bent at the waist in a V-shape.
