Drop in an Excel workbook with an X column and a Y column. The file is read here in the page; the regression is fitted by statsmodels, running in your browser. You get the fitted line, the scatter, R², and a coefficient table with standard errors, t-statistics, and p-values.

Drag a workbook here, or choose a file. Also reads .csv.
Each dot is one row. The line is the least-squares fit.
Your file is read in this page and never uploaded. Python itself is fetched once from the jsDelivr CDN.
