Hi There,
Among other things, I have profressional experience in time series analysis using R, Matlab and SAS and some of projects I have done in R are: modeling longevity risk using ARIMA, estimating regime shift in stock price using ARFIMA, and forecasting volatility using EMD,
I will need additional information in terms of what economic variable you want to forecast and its associated data to suggest a concrete timeline, plan and cost on this project.
Kindly let me know how you want to take it further.
