I have been doing the course for time series and they are talking about sunspots. From what I can see they have a time factor and a series factor. I have tried to apply this to stock prices using time and stock close price it seems to work. If I want to include other variables such as volume, adj close price, open price etc is it possible using the time series code in course4 week4. I have tried it and it complains when it comes to plotting the learning rate saying my time entry has shape of 100 and my series has a shape of 200 (I have volume and closing price). Any help would greatly be appreciated even if its saying I am on the wrong path and suggestion on what is a correct path. I have looked at kaggle and their approach seems a little different.
What exactly do you mean by “a series factor”?
thanks @TMosh. In my situation the time component would be the stock closing date. The series in this situation would be the stock closing price. Which is similiar to the sunspot example presented in the course. The time component in the coursework is when the sunspot is recorded, the series was the monthly average number of sunspots for that month. Instead of just having stock closing price does it make sense to have another factor like stock trade volume ?
