Automated data preparation
Import historical datasets and automatically clean null, non-numeric, zero, and negative values before distribution fitting.
Advanced distribution fitting
Evaluate multiple statistical distributions for each dataset and rank the results by goodness of fit to identify the most representative alternatives.
Statistical fit diagnostics
Validate fitted distributions through detailed statistics, comparative visualization, fit scores, and six dedicated diagnostic charts.
FlexFit
FlexFit is a complete Statistical Analysis module developed by EYF for FlexSim, designed to support data-driven statistical workflows across different industries and applications. It brings together data preparation, distribution fitting, validation, and comparison in a single integrated workflow.
The module processes one or more data files, treating each numeric column as an independent dataset. Before fitting, FlexFit automatically cleans the sample by identifying and removing null, non-numeric, zero, and negative values, providing visibility into the quality of the original data and the final sample used for statistical processing.
For each valid dataset, FlexFit evaluates multiple statistical distributions and generates a ranked list based on goodness of fit. Users can inspect distribution parameters, compare fitted curves, review descriptive statistics, and copy the selected distribution in a format ready for use in FlexSim.
From historical datasets to FlexSim-ready distributions
FlexFit provides a structured workflow for importing historical data, cleaning samples, fitting statistical distributions, validating results, and selecting representative distributions for use in FlexSim.
Native integration with FlexSim
FlexFit works directly within the FlexSim environment, extending its statistical capabilities with advanced data preparation, distribution fitting, validation, and diagnostic tools.
Users can process historical datasets, evaluate multiple statistical distributions, compare fitted results, and select the most representative distribution through a structured workflow designed specifically for FlexSim.
Once the fitting process is complete, FlexFit generates the selected distribution and its parameters in a FlexSim-ready format, reducing manual configuration and creating a direct connection between historical data and the statistical inputs used in FlexSim.
Integration capabilities include:
- Native FlexSim 3D environment
- Advanced distribution fitting
- Automated data preprocessing
- Descriptive statistical analysis
- Goodness-of-fit evaluation
- Advanced diagnostic visualization
- Distribution fit comparison
- Statistical parameter estimation
- FlexSim-ready outputs
What this enables:
- More representative statistical curves
- Deeper fit validation
- Clear identification of deviations
- Faster distribution comparison
- Greater confidence in fit selection
- Reliable statistical inputs for FlexSim

Diagnostic charts
FlexFit provides six complementary diagnostic charts to evaluate distribution fit from different statistical perspectives, allowing users to visually assess density, frequencies, cumulative behavior, residuals, quantiles, and probabilities.
Histogram + KDE + PDF · Frequency Comparison · Empirical vs. Theoretical CDF · CDF Difference · Q-Q Plot · P-P Plot
Summary panel
The Summary panel consolidates data quality indicators and descriptive statistics in a single view, providing visibility into the processed sample and its key statistical characteristics before distribution selection.
Data quality · Valid observations · Removed records · Minimum and maximum · Mean and median · Standard deviation
Exporting the diagnostic dashboard
FlexFit exports the complete diagnostic dashboard, consolidating all six statistical charts into a structured layout for technical documentation, reporting, and result sharing.
Six-chart dashboard · Dataset identification · Report-ready output
How Refit works
FlexFit provides an additional validation step by selecting the three highest-ranked distributions, generating synthetic samples from their fitted parameters, and fitting them again to determine whether the new result improves the original fit.
Top-three distributions · Synthetic samples · Automatic refitting · Fit comparison · Best-result selection · Additional validation
