Gradistat V 91 !!top!! Free Jun 2026

Unlike black-box machine learning, GradiStat shows you the iteration steps. You can literally see the log-likelihood converging. For teaching gradient analysis concepts, this transparency is invaluable.

GradiStat v9.1 is an older, freeware software package (often distributed via academic archives). This review reflects its functionality as a classic tool, not a modern cloud-based application.

: Handles input from standard measuring techniques like sieving and laser granulometry . Processing data in the free v9

This is the most popular method in GradiStat. Instead of using every single data point, it uses four specific percentiles (5%, 16%, 84%, and 95%) from the cumulative grain size curve to calculate statistical parameters. This method is less sensitive to extreme values ("outliers") in the tails of the distribution than the Method of Moments. Research comparing these methods has suggested that Folk and Ward measures, when expressed in metric units, often provide the most robust basis for routine comparisons of compositionally variable sediments.

is a specialized Microsoft Excel-based software used for the statistical analysis of grain size data in geomorphology and sedimentology. While the most widely documented versions are v4.0 and v8.0 , the software's core features remain focused on processing data from sieve or laser granulometer techniques.
