Hi!

Does anybody know what order of moving average (MA(q)) process should be used for the attached autocorrelation function of a variable?

Thank you

That sure looks like it has an AR component. Have you tried an AR(1) to start?

Yes I did for AR model. However, I am doing my coursework and the question is to build an MA model for the variable.
