Input feature scaling

In linear regression, if I scale the features, when testing the model must the input data be scaled the same way to get an accurate output?

i am sorry but i can’t understand you enough if you are asking about scalling the features its the same as the inputs , and its not about accurate output you scale to make it easily for you but its just an equations so the output will be the same if you scale it or not

Hello @adam_wilkes,

Yes, we need to treat training & testing data equally.
