Calling =TECHTO_MLREGRESSION for Machine Learning supervised regression in Excel is just a matter of copying and pasting

=TECHTO_MLREGRESSION in Excel is based on R and Python code from the Techtonique project’s Machine Learning supervised regression functions.

Here’s a unified way to use =TECHTO_MLREGRESSION directly and easily in Excel with xlwings Lite:

• If you haven’t done it yet, install xlwings Lite https://lite.xlwings.org/installation and click on its icon in the top right corner to open the editor

• Get a token from https://www.techtonique.net/token

• In the xlwings Lite editor, click on the dropdown menu > Environment variables

• Name the environment variable TECHTONIQUE_TOKEN, provide its token value, and push “Save”

• In the main xlwings Lite code editor (main.py), paste:

from techtonique_apis import techto_mlregression

• In xlwings Lite’s requirements.txt, paste:

xlwings==0.33.14  # required
python-dotenv==1.1.0  # required
pyodide-http  # required
black  # required
techtonique_apis

• Click Restart (or click “Restart” in the dropdown menu)

• Now you can close the xlwings Lite task pane, and Type =TECHTO_MLREGRESSION in a cell and select an input range (link to examples https://github.com/Techtonique/techtonique-apis/blob/main/examples/excel_formulas.xlsx). as long as the token is valid, it will work. It’s valid for 1 hour.

• Help for each function is here: https://docs.techtonique.net/techtonique_api_py/techtonique_apis.html. Or use Excel help for the function

• If you suddenly get VALUE error every time, check if the token is still valid (https://www.techtonique.net/token). It’s valid for 1 hour
