Mittevärtus

Mitteväärtus is an Estonian term used in data processing, statistics, and computing to denote the absence or inapplicability of a value in a given context. It literally means "non-value" and functions as a label for data points that do not carry a meaningful value for analysis or computation.

Usage and interpretation: Mitteväärtus is not a formal mathematical constant but a contextual designation. In data handling, a cell or observation marked as mitteväärtus indicates missing, unknown, or inapplicable information and may be treated by exclusion, imputation, or special handling in analyses or software.

Representations and related concepts: In practice, mitteväärtus may correspond to database NULLs, missing values, or placeholders such as a dash or empty field. In numerical computing it can be associated with values like NaN, depending on the system. The exact meaning and handling depend on the domain, data model, and software conventions.
