title: PACF and ACF plot does not show any significance
body: <p>I'm stuck in building my ARMA (ARIMA(p,0,q) model because of there's no significance at all in my ACF and PACF plot. I have read several articles about ARIMA but all of them at least shows significant correlation in their ACF and PACF plot. So for my case, i don't know what to do since this is my first time building times series forecasting model. My data is very stationary so i thought i could go on to build the model. But now i start to doubt if ARMA suits my problem. What should i do if i could still go on building the ARMA model? or should i use other algorithm?</p>
