Regression Tests
Theil–Sen Regression Statistical Calculator
Fit a robust line using the median of all finite pairwise slopes.
Calculated result
When to use
Fit a robust line using the median of all finite pairwise slopes.
Formula or algorithm
Theil–Sen slope is the median of pairwise slopes with distinct X values; the intercept is median(y - slope*x).
Assumptions and limits
Use the variable scales and sampling design required by this named statistical method. Review missing values, independence or pairing, outliers, and distribution or model assumptions before interpretation. Confirm that the selected dependent, independent, grouping, time, item, rater, or matrix variables match the research design.
Use Raw Data, Excel, or CSV
Upload XLSX, CSV, TSV, TXT, JSON, or pasted data where applicable; inspect cleaning, select the required variable roles, and review mapped inputs before calculation.
Uploaded files are processed locally in the browser. The cleaning report appears before variable dropdowns, and the selected cleaned columns are placed into this exact calculator rather than a generic fallback method.
About the Theil–Sen Regression Calculator
Fit a robust line using the median of all finite pairwise slopes. Regression calculators estimate an outcome relationship, model fit, coefficient uncertainty, predictions, and residual diagnostics for a specified model form.

How the Theil–Sen Regression Calculator Works
Theil–Sen slope is the median of pairwise slopes with distinct X values; the intercept is median(y - slope*x).
The calculation runs in your browser. Submitted values are validated for the required numeric range, data shape, units, and method-specific restrictions before a result is shown.
Assumptions and Checks
- Use the variable scales and sampling design required by this named statistical method.

How to Use the Calculator
- Confirm that the calculator title and method match the quantity, test, conversion, or planning question you need to solve.
- Enter values with compatible units and the requested sample, group, matrix, count, date, or option format.
- Select Example Data to inspect a valid input layout, or enter your own values and select Calculate.
- Review the result table, formula, worked substitutions, warnings, and interpretation rather than using only the headline number.
- Use Copy Result or Download CSV when you need a reusable record of the displayed calculation.
Understanding the Result
Interpret the estimate, uncertainty, test statistic, p-value, effect size, and diagnostics for the selected variables and design.
Inspect residuals, influential observations, collinearity, convergence, separation, and model specification before relying on coefficients or predictions.
Keep the entered values, units, selected options, and any warning shown beside the result. For a hypothesis test, report the statistic, degrees of freedom where applicable, p-value, alpha level, effect size, and decision. For an estimate or conversion, report the formula convention and final unit.
How to Report the Result
Report the method, selected variables, sample information, estimate or statistic, uncertainty, p-value when applicable, and practical conclusion.
Accuracy and Limitations
The calculator keeps full browser precision during calculation and rounds only for display. Accuracy still depends on correct inputs and on whether the displayed model represents the real problem. Educational calculators cannot replace required professional review, current official rules, field measurements, laboratory methods, or specialist statistical software where those are necessary.
