Least Squares
Least Squares computes and displays linear regression of 2D points. Below are some of the things you can do with this task:
To add data choose one of the following:
- Data Format: 2D points are white-space (blank) delimited pairs of numbers, for example x1 y1 x2 y2 x3 y3.
- Pasteboard: Copy the 2D points, click once to the left of the table headers, if needed click command-a to select all, then click the delete key and then paste the 2D points.
- File: Click the fetch tool and enter the absolute file path of the data you intend to import. Remember to use file:// as the prefix and another / to indicate absolute file path and then the file path. For example: file:///Users/steve/data.txt
- Web: Click the fetch tool and enter the URL of the data you intend to import. Remember to use https:// as the prefix and then the resource path. For example: https://www.vvi.com/data/points.txt
- Keyboard: You can click a table column or row header and delete or paste the entire column or row. You can also click on a cell to edit a particular value.
