Profile Summary

I am a statistician and time-series analyst specializing in tourism demand forecasting, hierarchical time-series models, and applied econometrics. My research focuses on cross-temporal forecast reconciliation for tourism and regional statistics. I have experience with ARIMA/ETS models, hierarchical and grouped time-series forecasting, regression, and general statistical analysis for research papers and reports. I can help you with data cleaning, exploratory data analysis, time-series modeling and forecasting, forecast reconciliation, and clear interpretation of the results. I provide well-documented, reproducible code (R or Python) and support in writing the methods and results sections of manuscripts or technical reports. I do not provide web or app development services. My work is focused on data analysis, modeling, and statistical consulting.
