Statistical analysis of soil properties per GOST 20522
For each engineering-geological unit the tool computes normative and design values of soil properties: it rejects outliers, calculates the coefficient of variation, and derives the soil reliability factor. Accepts data from AGS4 exchange files.

Standards
GOST 20522-2012: outlier rejection (table E.1), tα coefficient (table E.2), confidence levels 0.85 and 0.95.
Input
Individual test values per EGU, or an AGS4 file.
Output
Xn, X, V, γ per property, plus an outlier rejection log.
What it does
- Normative and design values for every EGU
- Outlier rejection by the ν criterion
- Coefficient of variation and soil reliability factor
- AGS4 import with breakdown by EGU

Questions
How many determinations are required?
Per GOST, at least six for mechanical properties and ten for physical properties.
Does it match hand calculations?
Yes, tables E.1 and E.2 in the reference are generated by the same engine function.
