I am working on a project, and I am absolutely new to forecasting and not so strong in statistics. I have an employee data for the last 7 years, along with the other variables like economic growth, employee turnover, vacancies, and some other economical factors. I have to do forecasting for the next 5 years. I have some questions:

  • Is it possible to do a time series analysis with more than one explanatory variable? Can this be done in R?

I would appreciate any kind of help. Thanks in advance!!

  • $\begingroup$ Can this question be reopend again please? I really need some help with the time series models in combinations with explanatory variables. $\endgroup$ – S.B Apr 25 '16 at 10:31
  • $\begingroup$ @Scortchi, perhaps off-topic is not a very good characterization. IMHO, the first question is valid but too basic (there is no such reason for closing, though), the second one is off topic while the third one is too broad. What if the OP deleted the last two questions? Would that be a good enough ground for reopening? $\endgroup$ – Richard Hardy Apr 25 '16 at 10:39
  • $\begingroup$ S.B., yes, time series modelling is possible with multiple explanatory variables. Multiple regression (possibly with ARMA errors), autoregression (possibly with exogenous variables) and vector autoregression (possibly with exogenous variables) could be your starting points. $\endgroup$ – Richard Hardy Apr 25 '16 at 10:41
  • $\begingroup$ @RichardHardy: The original version, prior to edits, contained only the 2nd question. I've re-opened the question, though it's perhaps rather broad even when focused on regression: a good answer should IMO include helpful references for someone new to time series analysis. $\endgroup$ – Scortchi Apr 25 '16 at 10:44
