I have done unit roots tests and noticed that two levels of differencing is required and 1 level of seasonal differencing is required. But after that when I am trying to plot the ACF and PACF plots I am not seeing any significant spikes. Everything is bounded within. How can I get the p, and q values in this instance ? Just calling the ARIMA function is also giving a random walk model which is not picking up the data atall. Can anyone tell what I can do in this instance ? Has anyone faced something similar before ?<\/p>\n<\/p><\/div>\n<p><!-- SC_ON -->   submitted by   <a href=\"https:\/\/www.reddit.com\/user\/NervousVictory1792\"> \/u\/NervousVictory1792 <\/a> <br \/> <span><a href=\"https:\/\/www.reddit.com\/r\/datascience\/comments\/1orxjwe\/questions_about_arima_modelling\/\">[link]<\/a><\/span>   <span><a href=\"https:\/\/www.reddit.com\/r\/datascience\/comments\/1orxjwe\/questions_about_arima_modelling\/\">[comments]<\/a><\/span>\n<\/div>\n<p> \t<BR><br \/>\n <BR><\/BR><br \/>\n    \/u\/NervousVictory1792<br \/>\n \t<BR><br \/>\n<BR><\/BR><br \/>\n<a href=\"https:\/\/www.reddit.com\/r\/datascience\/comments\/1orxjwe\/questions_about_arima_modelling\/\">Go to original source<\/a><br \/>\n \t<BR><br \/>\n <BR><\/BR><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Questions about ARIMA modelling I am facing weird issue trying to model my NET_DEMAND.
