Sometimes performing **Regression** will come up with different values than the simple linear equation returned by **Relate**. This happens because they use different methods of regression, **Regression** uses *M-estimation *by default and **Relate** uses *OLS (Ordinay Least Squares)*.

The regression method used in **Regression** can be seen by clicking the little cog like button on the right hand side of the card header, seen below:

Which will open the following dialog:

Choosing *OLS* for **Regression** will give results identical to a **Relate** of two numbers.
