StaTesc — statistics inside the number

Real life carries partial truth, ambiguous choices, and irrelevant-but-known information. StaTesc gives digits for each — so probability is not bolted onto arithmetic, it lives inside every numeral.

I. Motivation

Why statistics is foundational, not downstream

Classical arithmetic assumes complete information: every digit is fully known. StaTesc — the digit algebra defined in LaeStaDesc — generalises that assumption. Each digit is read as a triple φ(d) = (s, t, u) of spatial truth, temporal truth, and uncertainty. Ordinary numbers, Boolean values and Kolmogorov probabilities are recovered as special cases when u = 0.

II. Digits

The StaTesc digit set 𝒟

Ten symbols cover the interior life of numbers. Three are used most often: U for spatial uncertainty, for temporal uncertainty, and for structural absence.

Spatial uncertaintyU
Either A or O — a 50/50 spatial value carried inside the digit itself.
Temporal uncertainty
Either I or E — a 50/50 temporal value; time-band ambiguity as a numeral.
Bound uncertainty
Companion to ∪ — restricts the temporal ambiguity to a resolvable band.
Upward reversibleV
Uncertainty that propagates up the positional band; useful for unknown future effects.
Downward reversibleW
Mirror of V — known but currently irrelevant details that resolve downward.
Structural absence
A digit that is not a digit — placeholder for missing data, optional fields, gaps.
III. Operations

Three operations, three axioms

AND behaves as multiplication, OR as addition, NOT as unary minus — the same shapes classical arithmetic uses, but uncertainty propagates through them coherently. The whole system rests on three axioms:

  • Associativity. Regroup freely; results agree.
  • Band-precedence. Temporal meaning dominates spatial meaning when they meet.
  • Uncertainty monotonicity. AND increases uncertainty, OR decreases it.

Lifting these digit-wise operations to numbers gives an arithmetic in which "known", "unknown" and "structurally absent" travel side by side. See section 4 of the LaeStaDesc README for the full multi-band operator table and its correspondence with Logecs connectives (MULT, ADD, NOR, XOR, NET).

IV. Where it fits

Statistics as an interface layer

StaTesc is the interface between Real Logecs (numbers and truth) and Natural Logecs (measurements and populations). Every reading of a physical instrument already lives on this layer; StaTesc simply lets it be written down without a separate probability apparatus.

Because the digits are octave-symmetric — every band rescales by two — statistical numbers stay recognisable when zoomed in or out, the same self-similarity that makes tones repeat across octaves:

Octave self-similarity×2 / ÷2
Each step halves wavelength and amplitude — the whole plane scales by two, so shape is preserved.
