Egger Regression Test Calculator
Test funnel-plot asymmetry using standardized effects regressed on precision.
Calculated result
When to use
Test funnel-plot asymmetry using standardized effects regressed on precision.
Formula
Standard normal deviate = intercept + slope × precision; test the intercept against zero.
Assumptions and limits
Use the named design, correct variable scale, independent or paired structure as specified, transparent missing-data handling, and an adequate sample before interpreting inference.
Method integrity
This page uses a separate canonical calculator ID, method-specific inputs, a dedicated calculation branch, an automated fixture, and no generic fallback result.
Use Raw Data, Excel, or CSV
Upload XLSX, CSV, TSV or pasted data, review cleaning, then select the dependent, independent, grouping, paired, time, item, rater or study variables required by Egger Regression Test.
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.

How the Egger Regression Test Calculator Works
Standard normal deviate = intercept + slope × precision; test the intercept against zero.
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
- The study design and variable scales match the named method.
- Independence, pairing, ordering, censoring, grouping or rater structure is represented correctly.
- Missing values and influential observations are reviewed before inference.
Required Inputs
- Study effect estimates (required)
- Study standard errors (required)
Results Reported
The result panel shows the final answer together with the intermediate quantities needed to audit the calculation. Depending on this method, reported values include:
- Studies
studies - Egger Intercept
egger_intercept - Standard Error Intercept
standard_error_intercept - T Statistic
t_statistic - Degrees Of Freedom
degrees_of_freedom - P Value
p_value

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
Review the Egger Regression Test estimate or test statistic, uncertainty or p-value where applicable, assumptions, chart and research-question interpretation.
Review the formula, units, assumptions, and result interpretation before using the calculation.
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 Egger Regression Test, the analyzed variables and valid sample size, the principal estimate or statistic, degrees of freedom and p-value or confidence interval where available, assumptions, and a conclusion tied to the research question.
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.
