I apologize for the slightly out of place question but I figured the great resources here could help
My issue is that I have time-series data that trends nicely expect for this last quarter where the data generating process was changed. now some of the estimates don't trend. are there any statistical techniques i can apply to smooth out the data? i only have this last data point using the new data-generating process.
Thanks for your help,
also if you'd like to recommend a statistical/econometric forum where you think this question would be better served i'm all ears.
