Regression Analysis Tool

Linear regression lets you quantify the relationship between one or more input variables and an outcome — for example, how ad spend predicts revenue, or how impressions and clicks jointly predict conversions. This tool runs ordinary least squares regression in-browser with no server required. You can enter your own data in a spreadsheet-style grid, upload a CSV file with your campaign or sales data, or load one of the built-in presets to see how the tool works.

Switch between Plain English mode for a practitioner-friendly summary of the relationship and what it means, and PhD Mode for the full OLS output table — R², adjusted R², F-statistic, standard error of the regression, all beta coefficients, and a row-by-row residuals table. After running a regression, enter new X values to generate a point prediction from the fitted model. Supports simple regression (one predictor) and multiple regression (up to several predictors).
