About this tool
The Linear Regression tool fits a straight line to a set of (x, y) data points and reports the slope, intercept, and correlation coefficient. The result is plotted so you can see the fit visually.
Common use cases
- Estimate the trend behind a small dataset, such as sales over recent weeks.
- Check how strongly two variables move together before building a heavier model.
- Produce a quick prediction line for a report or presentation.
- Demonstrate the basics of regression to students or junior analysts.
