Regression coefficient plot

Compares regression estimates and their uncertainty on a shared effect scale.

The question

Which factors most affect basket value in our model?

Model coefficients with 95% intervals (EUR change in basket value)

When to use it

Use it when

Summarising regression coefficients with uncertainty.

Avoid it when

Comparing raw coefficients across incompatible units as importance scores.

How to read it

Read term names, estimates and intervals on a common scale.

Note

Interpretation depends on variable units and model specification.

The data you need

Layout
Wide interval summary
Fields
Study or Term: text; Estimate,Lower,Upper: numbers
One row is
One estimate and its lower and upper interval bounds. What is the grain?
Rules
Keep a common effect scale and specify the no-effect reference. Log-scale ratio effects require positive bounds.
Optional
Weight,Group,PooledIndicator,ModelName.
Preparation
Extract coefficient estimates and valid uncertainty intervals, keeping effect units and transformations explicit.
Units
Coefficient units depend onpredictor andoutcome scales; exponentiated ratios use no-effect 1, additive effects often 0.
Example of the input layout: Wide interval summaryA wide table: one row per item, with a separate column for each measure or period.Study or TeEstimateLowerUpper…ABC
A wide table: one row per item, with a separate column for each measure or period.

Worked example
