How can I find "evaluateFit" function of matlab?

load carEcon
whos carData carTrain carTest
mdl = fitlm(carTrain);
econPred = predict(mdl,carTest);

Plot the results. I used it in MATLAB machine learning course, however when I am using evaluateFit in my own version, it is not working.

evaluateFit(carTest.FuelEcon,econPred,"Linear Model")

I can't find any evaluateFit function in the MATLAB documentation -- fitlm uses

plot(mdl)

for basic plot; many additional options available.

Which machine learning course are you speaking of? There must have been something specifically produced for it.

I was taking about the course "Machine Learning with MATLAB" which is offered by MATLAB. evaluateFit is a function that produces the following plot where plot(mdl) will not provide the same output.

Well, you'll need to see about where that course is, then, because the function isn't in the standard MATLAB distribution nor any toolboxes.

There are examples using plot() and the fitlm model and you could produce the same plot sequentially from it...but not as conveniently as a prepackaged routine, granted.

Without a link to the training/course, just looking, don't know there's anything can do...

Thank you. I can give you the link of the course. If you go to the subsection linear models(ex.11) under section Regression methods, you will find it.
