How can I extrapolate data using regression learner app?
显示 更早的评论
I have great solutions using the regression learner app. If I export the model and use the same data, then the result differs a lot from the solution in the regression app. I have already read the documentation, but this does not help. Is there someone how is more familiar with this methodology?

You have not posted what you are doing or the model you are using, so I suggest that you click on Export Model, then post the exported code for your model here.
Extrapolating to a small extent can work for some models, although for others (such as polynomial models), it can produce inappropriate results. As a general rule, it is best not to extrapolate beyond the region of fit.

after you export the modle to - "trainedModel", you can predict simply by -
yfit = trainedModel.predictFcn(data)
For 1d simple interpolation i would suggest interp1 with extrap option. becuase with this regression you need to have a better understanding of what you are doing.
