EIME

EIME (Estimator of Indirect Measurement Errors) takes measurements and a formula as input and subsequently uses it to estimate measurement errors and calculate values using a given formula.

Usage

Julia is required to use EIME, you can install it from https://julialang.org/downloads/

Via CLI:

julia eime.jl [in.eime.jl]

[in.eime.jl] is to be substituted for a path to an input file.

Input

EIME takes a single argument - path to a Julia source file - and evaluates it.

You can write any Julia code in an input file, but for the estimator to work properly you have to define the following variables:

• f - main formula for calculations
• measurements - a named tuple of measurement values
• errors - a named tuple of systematic error values

And optionally:

• label (default: "f") - escaped label for the main value to be calculated
• unit (default: "") - string that will denote the unit of the main value
• digits_after_decimal_point (default: 4) - number of digits after decimal point

See in.eime.jl for more information.

See in.eime.example.jl for an example.

Output

EIME outputs a minimal LaTeX string that documents every step of estimating errors for given measurement data. It may then be rendered by a LaTeX renderer like MathJax.
