Every number comes from a computed table.

XENDB computes on your computer; the XENTHK model writes the words. Before an answer is shown, every number in it is checked against the tables behind it. An answer with a number no table holds is not shown.

An answer and its evidenceNumbers from car_prices.csv, a public dataset of 558,837 used-vehicle auction sales.

Which state has the strongest demand for used cars?

Florida has the highest observed sales activity in this data.

Florida recorded 82,945 sales, California 73,148 and Pennsylvania 53,907. T1

Texas follows with 45,913 and Georgia with 34,750. T1

Descriptive claimNo causal claim

Method: count of sales by state over 558,811 rows; 26 shifted rows left out at your request.

What it does

  • The model never does the arithmetic

    Totals, counts, averages, spreads, rates and correlations are computed by XENDB from your rows. The model reads the results; it never adds, divides or rounds.

  • Each finding cites its table

    Every finding links to the table it came from, with the fields and rows that went in.

  • Claims stay inside the evidence

    A proxy stays a proxy: completed sales are sales activity, not demand. Correlation is reported as association, never as cause. A difference is not called significant without a test.

  • The method is shown

    Each answer says what was computed, on which fields, over how many rows, and which rows were left out at your request.

Limits today

  • Routes today: ranking, trend, distribution, relationship, ratio and KPI. XENTHK describes what the data records; it does not forecast.
  • When a number cannot be traced to a table, the answer is withheld rather than shown with a guess.
