Responsibilities

• Develop and maintain statistical, econometric, and time series models to forecast passport demand.
• Apply forecasting methods such as regression, ARIMA, exponential smoothing, state space models, Bayesian methods, and other appropriate techniques.
• Develop simulations and scenario analyses to evaluate uncertainty and potential future outcomes.
• Perform model validation, backtesting, sensitivity analysis, residual analysis, and forecast error evaluation.
• Analyze historical demand, survey data, economic indicators, demographics, travel trends, policy changes, and other potential demand drivers.
• Evaluate model assumptions, data quality, structural changes, bias, and sources of uncertainty.
• Compare alternative modeling approaches and recommend methods based on accuracy, interpretability, and statistical rigor.
• Monitor actual demand against forecasts and identify opportunities to improve model performance.
• Communicate methodology, assumptions, uncertainty, and analytical findings to technical and nontechnical stakeholders.
• Maintain reproducible analytical workflows, model documentation, and technical artifacts.

Requirements

• Bachelor's degree in Statistics, Econometrics, Economics, Applied Mathematics, Operations Research, or another highly quantitative discipline.
• Ability to operate efficiently using new and emerging tools of quantitative analysis.
• Experience in statistical analysis, forecasting, econometrics, predictive modeling, or related quantitative analysis.
• Strong knowledge of regression, probability, statistical inference, time series analysis, model validation, and uncertainty.
• Experience developing and evaluating forecasting models using ARIMA, regression-based forecasting, exponential smoothing, state space models, or comparable methods.
• Experience with simulation, scenario analysis, or probabilistic modeling.
• Experience validating models through backtesting, sensitivity analysis, residual analysis, or out-of-sample testing.
• Proficiency with Python, R, Stata, SAS, MATLAB, or comparable statistical tools.
• Strong analytical, problem-solving, and communication skills.
• Ability to independently structure and solve complex quantitative problems.
• Master's degree or PhD in Statistics, Econometrics, Economics, Applied Mathematics, Operations Research, or a related discipline.
• Experience with demand, economic, population, workload, or other longitudinal forecasting.
• Experience with Bayesian methods, Monte Carlo simulation, multivariate time series, or advanced econometric techniques.
• Experience analyzing survey data, including sampling, weighting, representativeness, and sampling error.
• Experience with Python statistical libraries, Stata, or R.
• Experience working with economic, demographic, travel, public policy, or government administrative data.
• Experience developing or evaluating simulation models and scenario-based forecasts.
• Experience supporting federal government customers.
