Uncertia
Build transparent measurement-uncertainty budgets with source distributions, sensitivity coefficients, variance contribution, effective degrees of freedom, and export.
Focused field tools
Define exactly what quantity is being estimated, under which conditions and method.
Write the functional relationship before listing convenient uncertainty sources.
Derive statistical contributions from an appropriate observation series and degrees of freedom.
Use certificates, resolution, specifications, experience, and physical limits with stated logic.
Divide a symmetric half-width by square root of three when values are equally probable.
Divide by square root of six when central values are more plausible than bounds.
Uncertia supports transparent GUM-style calculations and audit discussion. Confirm the measurement model, dependence and covariance, source distributions, divisors, sensitivity coefficients, degrees of freedom, traceability, and reporting rules with your laboratory procedure.
