Upload a spreadsheet.
Get the statistics, explained.
Tell StatEVN what you want to find out. It cleans your data, picks the right model, runs the checks a statistician would, and writes the result as sentences you can act on.
Free to start, with no credit card. Works with CSV, Excel and JSON files, or just your A/B test totals.
One file and a question. That is all it needs.
No scripts, notebooks or setup. Most runs take under 30 seconds from upload to a written result.
Upload your file
Sales figures, survey answers, financial records, web traffic. Any table in CSV, Excel or JSON.
Say what you want to know
Pick the column you want to explain, like revenue or churn, and the columns that might drive it. Or just type your goal.
StatEVN picks the model
It cleans the data, runs the diagnostic tests and chooses a model that suits your data and your goal.
Read what it found
Every effect is explained in a sentence, with charts and the full statistics one click away. Export to Excel or PDF.
It runs the checks a statistician would.
Real models, tested for trust before they tell you anything.
- RegressionBreusch-Pagan, White
Are the errors uneven? This decides the model.
- ForecastADF, KPSS
Is the series stable enough to forecast?
- RegressionVIF
Do two inputs overlap too much?
- RegressionDurbin-Watson
Does one error carry over to the next?
- Every modelHeld-out test rows
Does it predict data it never saw?
What-if simulator
Move an input and watch the prediction change.
Two reading levels
Plain sentences, or the full statistics.
A/B tests
Significance, lift and the sample size you need.
Compare models
See which model predicts best on the same data.
Reports
Excel and PDF, ready to send.
Recent analyses
Reopen a past result without rerunning it.
16 models. You don't have to pick one.
StatEVN reads the shape of the column you want to explain, the diagnostic results and the goal you typed, and chooses for you. You can still choose yourself.
Prediction
How much, how many, what value
- Linear regression (OLS)
- GLM, four families
- Random Forest
- Gradient Boosting
- XGBoost
- Decision Tree
Classification
Yes or no, which group
- Logistic regression
- Random Forest
- Gradient Boosting
- XGBoost
- Decision Tree
Clustering
Which customers or items belong together
- K-Means
- Hierarchical (Ward)
- DBSCAN
Forecasting
What happens next month and after
- ARIMA
- SARIMAX
- Exponential Smoothing
- Prophet
Also included: t-tests and ANOVA to compare groups, Monte Carlo simulation for what-if scenarios, and the A/B test tool.
Did version B really win?
Enter your visitors and conversions, or upload a file. StatEVN tells you whether the difference is real, how big it is and how much longer to run the test.
- Significance
- Real difference, or chance
- Lift
- How much better, in percent, with a range
- Sample size
- Plan the test before you start it
- Segments
- Up to 10 versions, or hundreds of segments
Version B converts 23% better, and the difference is real.
