I am working on a time series problem with a single variable which has consecutive zeroes at different periods. The TS plot looks like this: Upon closer examination, the variable has consecutive zeroes in between spikes of activity.
Following are the acf and pacf plots. I am not quite able to wrap my head around these.
Any pointers on which techniques could be used to develop a forecast model for such data?
EDIT: Because the initial time series plot looked very much like a stationary differenced series, i tried to apply a inverse (discrete integration) on it.
