Functions are powerful tools that allow you to perform complex analysis, while still having access to your entire database. Learn more about how to use functions. These guides are meant to be used on an as needed basis, when you need more in-depth knowledge about a specific function. Basic function guidance is built into Sigma. Start typing a function name, and Sigma provides you the context you need to complete the formula.
When you type in a function, Sigma provides you a description of the function, descriptions of the arguments needed for the function, and a link to the in depth function documentation. You can also click fx on the left hand side of Sigma's formula bar any time to open this function index page.
