  • I was hoping someone may be able to clarify something for me. I am trying to do a timeseries forecasting with the GaussianRandomWalk function in PyMC3. I have been suggested that my code is wrong as I’ve modeled it so that the standard deviation of the latent walk is the same as the observation noise, which seems like it might be a mistake. Time series represent the time-evolution of a dynamic population or process. They are used to identify, model, and forecast patterns and behaviors in data that is sampled over discrete time intervals. To create a timeseries object, use the timeseries function with input arguments that describe the data samples.

I am coming from a background of using statistical models:ARIMA, GARCH on timeseries. To start I want to implement a simple Bayesian feed-forward neural network on a timeseries data. What I am thinking to do is to set AR & MA values of a univariate timeseries as the priors for my model.Therefore analyze their distribution to build my posterior.
