Instead of training a model on the whole series of call volume, you might be better off feeding your model one day at a time, that is you cut the time series between 8 am and 5 pm every day. After all, you do not want your model to spend parameters on learning that no calls are made at night or during the weekend. Plus you can add the day of the week as a parameter in the model
May 21, 2018 at 8:39 comment added Gino_JrDataScientist Is this the training data? Make sure that you are testing your models on an independent sample. A common way is to split the dataset in two, train on one (say time between 0 and 500) and test on the other. Then look at the R2. The reason I'm asking is that I am very surprised to see such good results.
