Estimaatteihin
Estimaatteihin is the illative plural form of the Finnish noun estimaatti. In Finnish, estimaatti is used in technical contexts to refer to an estimator in statistics or, less technically, to an estimate depending on context. The illative case marks direction toward or inclusion in something, and the plural illative suffix -iin/-ihin yields forms such as estimaatteihin. In practice, the form signals “into the estimators/estimates” or more broadly “to the estimates” when the surrounding text treats estimators or estimates as a defined set.
The term is primarily found in scientific and technical writing, particularly in statistics, econometrics, and measurement
