Google Drive script for doing regression analysis of spreadsheet data. Builds on the regression script by Tom Alexander: https://github.com/Tom-Alexander/regression-js

Select x and y data by click-and-drag in the spreadsheet, then run "regression analysis" from the menu and select the relevant function type. (Data must be in columns, with x values in the first selected column.) Use the button "Build scatter plot" to have the regression-fitted data plotted in a chart, in a new sheet.

You have three different options for installing gRegression:

1: Search the scripts available for installation through the standard Google interface (from "install" -> "scripts").

2: Use this link to copy a spreadsheet already containing the code: https://docs.google.com/spreadsheet/ccc?key=0AjgECFpHWbvRdGFXeFNrbWUyV05FVTE2bHZFTXM4WWc&newcopy

3: Use the source code found here on GitHub and paste it into the code editor in a Google spreadsheet. If you do, you will also need to add the code from regression-js manually (see link to Tom Alexander's project above).
