bootstrappausta

Bootstrappausta is a Finnish neologism used in discussions of statistical resampling methods, especially bootstrapping. The term fuses bootstrapping with the Finnish suffix -usta, which marks a process or activity, to denote the act of performing bootstrap-based inference. It appears in Finnish-language textbooks, lecture notes, and online discussions, mainly from the 2010s onward. There is no official definition published as standard terminology, and usage can vary between authors.

In practice, bootstrappausta refers to drawing samples with replacement from observed data and computing the statistic of interest across resamples to estimate standard errors, confidence intervals, or bias corrections. Common variants discussed in Finnish texts include percentile bootstrap, BCa intervals, and bootstrap-based model validation. The concept is taught in introductory statistics courses and used in applied research across social sciences, biomedicine, and economics.

Because it is informal, bootstrappausta may be confusing to readers unfamiliar with bootstrapping or with Finnish-English code-switching. In formal writing, authors usually use bootstrapping or resampling and reserve bootstrappausta for colloquial or didactic contexts.
