Gradistat V 91 Free -

  • Skewness: positive (fine skewed) vs. negative (coarse skewed) distributions suggest depositional processes or post-depositional reworking.
  • Kurtosis: peaked vs. flat distributions; sensitive to tails and sample size.
  • Grain-size distribution analyses:
  • Standard methods implemented: Folk & Ward (1957), Trask (1932), graphical methods (e.g., cumulative curves), and moment method. Options to switch between protocols or report multiple methods for comparison.
  • Export and reporting: export tables and plots to common formats (CSV, TXT, PNG) and generate printable summary reports.
  • Batch processing: apply analyses across multiple samples and compile comparative tables and plots.
  • Quality control: error checking for inconsistent input (non-monotonic cumulative percentages, negative sizes), and warnings for small sample sizes that can bias statistics.

    • Gradistat V91 is an older Windows utility for analyzing and processing granulometry data, widely used in geology, sedimentology, and civil engineering for grain-size distribution, statistical parameters (mean, median, sorting), and plotting cumulative and frequency curves.

    The software computes up to 14 statistical parameters using three different methods:

    GradiStat v9.1 Free is not "good" in the modern sense of software design. But it is correct for a narrow, historic purpose. gradistat v 91 free

    Download it if: You need to run a classic Gaussian logit regression on a single gradient, you have fewer than 200 samples, and you hate installing R packages.

    Skip it if: You want to visualize your data, handle multiple gradients (multivariate), or expect any customer support. Skewness: positive (fine skewed) vs

    Pro Tip: Run your data through GradiStat v9.1 to get the numeric optima, then immediately copy-paste those numbers into Excel or R for plotting. Do not attempt to use GradiStat for final figure generation.

    Gradistat v 9.1 is free, but it has limitations: no 64-bit Excel support, no automatic batch processing, and it can be unstable on modern Windows 11 with newer Excel. Here is how it stacks up:

    | Feature | Gradistat 9.1 Free | Gradistat (commercial successor) | GSlope | R package ‘G2Sd’ | | --- | --- | --- | --- | --- | | Price | Free | Paid (~$100-200) | Free | Free | | GUI | Excel-based | Standalone | Standalone | Command-line | | Batch processing | No | Yes | Yes | Yes | | Hydrometer support | Yes | Yes | No | Limited | | Modern OS support | Partial (Windows only) | Full | Full | Cross-platform | | Learning curve | Low | Low | Medium | High |

    Verdict: Gradistat 9.1 remains best for students, quick analyses, and legacy data compatibility. For large-scale research (>100 samples), consider a modern tool.
