What is the bootstrap process?
A bootstrap is the program that initializes the operating system (OS) during startup. The term bootstrap or bootstrapping originated in the early 1950s. It referred to a bootstrap load button that was used to initiate a hardwired bootstrap program, or smaller program that executed a larger program such as the OS.
- Bootstrapping in business means starting a business without external help or capital. Such startups fund the development of their company through internal cash flow and are cautious with their expenses. Generally at the start of a venture, a small amount of money will be set aside for the bootstrap process.
- The software was formerly known as Twitter Blueprint and is sometimes referred to as Twitter Bootstrap. In computers, the word bootstrap means to boot: to load a program into a computer using a much smaller initial program to load in the desired program (which is usually an operating system).
A bootstrap sample is a smaller sample that is “bootstrapped” from a larger sample. Bootstrapping is a type of resampling where large numbers of smaller samples of the same size are repeatedly drawn, with replacement, from a single original sample. You randomly draw three numbers 5, 1, and 49.
- Bootstrapping is a useful technique for testing model stability. IBM SPSS Bootstrapping helps make it effective and easy. This module of IBM SPSS Statistics estimates the sampling distribution of an estimator by resampling with replacement from the original sample.
- 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)
- An increasingly common statistical tool for constructing sampling distributions is the permutation test (or sometimes called a randomization test). Like bootstrapping, a permutation test builds - rather than assumes - sampling distribution (called the “permutation distribution”) by resampling the observed data.
