Hi,

I hope the answer to this isn't staring me in the face...but I'm trying to use the 'addTerms' function

https://www.mathworks.com/help/stats/linearmodel.addterms.html

and I cannot figure out from the documentation what toolbox I need to download in order to use it.

I already have the 'Statistics and Machine Learning Toolbox' version 12.3. However, my MATLAB install is not recognizing the 'addTerms.m' function.

Thanks for your consideration,

tom

See the upper-left corner of the doc page. In this case, it is the Statistics and Machine Learning Toolbox.

Walter is correct. You can see this by scrolling down to the Input Arguments section on that documentation page, which lists as the description of the mdl input argument:

"Linear regression model, specified as a LinearModel object created using fitlm or stepwiselm."

If you tried to call addTerms with something that's not a LinearModel object as the first input, that doesn't satisfy the requirements of the function and so MATLAB throws an error.
