Time series analysis help • /r/MachineLearning

I arrived at time-series analysis models that seemed to be suited to the task, but I'm hitting some issues I would appreciate some help with. I haven't really done any ML on timeseries data or autoregression so this is kind of new to me. First of all, the nature of my data is dense measurements of a particular value over time. The seasonality of the data is probably both weekly and daily. When looking for timeseries models for seasonal data, nearly all the sources suggested a SARIMA model.
